CalMod 1.1

This being Silicon Valley, future plans for Caltrain modernization are known as CalMod 2.0, the next big thing beyond the CalMod 1.0 improvements that are already under contract.

CalMod 2.0 is a list of future improvements worth about $750M that includes:
  • Full fleet conversion to 8-car EMUs ($440M)
  • Broadband connectivity ($30M)
  • Maintenance facility improvements ($36M)
  • Level boarding and platform extensions ($250M)
In the grand scheme of things, these aren't outrageous expenses ("only" another 38% over and above the $2B tab for CalMod 1.0), but they're not cheap, either. To meet capacity challenges in the short term, possibly concurrently with delivery of CalMod 1.0, perhaps some of these expenses can be moved up to realize the maximum bang for the buck as soon as 2021.

CalMod 1.1 would consist of just two line items:

1) Lengthen EMUs to 8 cars, for $145M

The EMU fleet for CalMod 1.0 consists of sixteen 6-car trains, with a reduced seating capacity of 558 that has caused much yammering amid the increasing load factors during peak commute hours. Even without a ridership bump from the "new and modern" effect, it is likely these trains will be packed from day one. Now is the time to start doing something about it.

Seating layout for two extra cars (based on Stadler brochure)
Two unpowered cars would seat up to 264 passengers.
The contract with Stadler includes an option for another 96 cars priced at $390M, a figure larded up to $440M in the CalMod 2.0 total presumably due to the usual procurement overheads. This figure is for 100% fleet replacement, with all the remaining diesel consists being retired. In the short term, only 1/3rd of the option cars would need to be exercised; this involves purchasing 32 cars or 2 extra cars for each of the sixteen EMU consists in the CalMod 1.0 order.

The per-train capacity will increase by well over 200 seats per train, back to a level that will mitigate peak hour crowding. However, 8-car EMUs will exceed the length of many of the existing platforms.

2) Extend platforms to a minimum length of 700 feet, for $25M

Platform extensions are relatively cheap to build, especially when you don't need to rebuild the entire length of station platforms as would be needed for level boarding. You can leave vertical circulation (stairs, ramps) and amenities (vending machines, lighting, benches, PA system, departure boards, etc.) alone and just tack on a short length of concrete, and perhaps move a pedestrian crossing. Caltrain excels at building platforms and has done so extensively, pouring some 5 linear miles of platforms over the last 18 years!

The length of Caltrain's existing platforms is documented in this schematic of California rail systems. To dock an 8-car EMU, platforms need to be extended to at least 700 feet. The necessary extension lengths are graphed at right; labels show the year of completion of each platform's construction.

The total amount of platform extension required to operate 8-car EMUs is approximately 3500 feet. This figure excludes Hillsdale and South San Francisco, both of which are already slated to be rebuilt to 700 feet. Each foot of platform costs about $7000 to build, on the basis of a typical $10M cost for two 700-foot platforms from past platform reconstruction projects. Therefore, the tab for extending all platforms to 700 feet (for the time being, at their current height of 8 inches) lies in the range of $25M.

Start Planning Now

The bottom line: another $175M or an extra 9% investment over CalMod 1.0 yields an extra 23% peak hour seated capacity for CalMod 1.1. It would be best to start planning for CalMod 1.1 now, and to turn CalMod 2.0 into the big level boarding project for the 2020s. In software parlance, the CalMod 1.1 patch should be applied immediately upon release of CalMod 1.0.

Core Capacity Math

With federal funding for Caltrain modernization on indefinite hold, a diverse flock of vultures have started circling the skies over the peninsula corridor--opponents of electrification, boosters of peninsula BART, opponents of high-speed rail, and detractors of rail or transit in general. Some opponents have latched on to a perceived vulnerability of the modernization project, using a legal parsing of federal regulations to allege that Caltrain's application for federal transit funding is fraudulent and illegal. This sensational claim merits closer examination.

FTA "Core Capacity"
The $647M of funding that Caltrain has pursued for several years, and came agonizingly close to obtaining, is allocated by the Federal Transit Administration and disbursed by congress under a competitive grant program known as a Capital Investment Grant or nicknamed "5309," after the section number of the United States Code under which the program is defined. One of the ways to obtain federal funding under this program is to increase the capacity of an existing transit system by at least ten percent. This is known as a "core capacity" grant, the type that Caltrain is pursuing.
The fracas is all about this ten percent, and whether Caltrain is actually meeting the criteria for eligibility.
To prevent gaming of the system, section 5309 policy guidance specifies how that ten percent increase is to be counted for a core capacity project to become eligible for funding. Importantly, the FTA makes an artificial distinction between "light rail / heavy rail" (where passengers traditionally sit and stand) and "commuter rail" (where passengers traditionally only sit) that fundamentally changes the metric used to measure capacity.
  • Light rail / heavy rail capacity is measured by "peak hour person capacity in the peak direction," a measurement that includes standees and is based on floor space.
     
  • Commuter rail capacity is measured by "peak hour peak direction seated load," a measurement that excludes standees and is based solely on seat count.
Under this uniquely American taxonomy, Caltrain is an odd duck: the modernization project seeks to transform it from a traditional diesel commuter train into a swift and frequent transit system whose attributes will bear a closer resemblance to a heavy rail system like BART than to a stereotypical American commuter train. Indeed, Caltrain's choice of a Swiss train design underscores the cultural disconnect with the rigid system of American train categories.

If you needed any more proof, BART is removing seats to increase capacity!

EMU seating capacity
As ordered, Caltrain's EMUs will have significantly fewer seats per train  than today's six-car diesels. EMUs are not a magical technology: they may lack a locomotive, but all the traction components that would normally be found in the locomotive still need to be accommodated elsewhere in the train. In a preliminary brochure of Caltrain's new EMUs, the traction bits show up as cabinets marked with a spark symbol. These things take up space, so a six-car EMU offers fewer seats than a traditional six-car train hauled by a diesel locomotive.

(In passing, some have blamed the lower seating capacity of the Stadler EMUs on the dual door configuration. A cursory review of proposed seating layouts can retire this fallacy.)

The seating capacity directly counted from the brochure was 573 seats per six-car EMU, although Caltrain's FTA grant application assumes only 558, averaging just 93 seats per car.

A Shifting Baseline
Ten percent, but compared to what? The baseline present-day capacity is also contentious, since Caltrain's record ridership has created the need to provide more seats today.
In Caltrain's September 2016 grant application materials and correspondence with the FTA (helpfully obtained under a Freedom of Information Act request by CARRD Morris Brown), the capacity baseline is tabulated as 3403 seats per peak hour per peak direction, with a net increase of 365 seats (barely squeaking by with a 10.7% increase) to a total of 3768 after the modernization project is completed.  Detailed tabulation is provided below, as extracted from the grant application.

Total During the Peak Hour


3,768

Opponents have pointed out that well before the date of the FTA grant application, train 225 was converted to a six-car Bombardier consist seating about 790 passengers, as was train 217, thus increasing today's peak hour baseline by 170 + 185 = 355 seats, and cutting the future capacity increase fully in half from 10.7% to an ineligible zero percent 5%. Caltrain may have done itself in simply by serving its customers today.

How to solve the FTA seating equation
To meet the FTA requirements without question, and to shoo those vultures away, here are some solutions Caltrain could reasonably pursue:
  • Build the train cars 3.2 meters wide with five-abreast seating on the upper deck (the lower deck would remain four-abreast with a wider aisle). A car width of 3.2 meters is within the AAR Plate F loading gauge that is cleared to operate on the peninsula corridor, and is a common width in East Coast commuter railroads (the LIRR M7, the Metro North M8, and the SEPTA Silverliner V are all 3.2 meters wide with sections of five-abreast seating). Why Caltrain hasn't already pursued this is baffling, because it is a low-cost and high-benefit change regardless of FTA rules. The Stadler KISS EMU that Caltrain ordered has previously been delivered in widths up to 3.4 meters. This design change is worth +64 seats per six-car EMU, or +256 seats/peak hour, or +7.5% core capacity.
     
  • Increase the size of the initial EMU order.  This is a tough sell, given how hard it has been to fund the modernization project, but the relative cost increment is minor when considered in proportion to the entire budget. The Stadler contract already includes an additional 96 cars under a fixed-price option, 32 of which (one third) could be exercised to make all 16 of the EMUs on order eight cars long.  The incremental cost would be another $130M (one third of $390M, or less than 7% of the entire value of the PCEP project), and the seating capacity would go up by +186 seats per EMU, or +744 seats/peak hour, or +21.9% core capacity.  That's right: for an extra 7% cost you can triple the capacity increase.
     
  • Both measures applied together would increase seating capacity by +272 seats per EMU, or +1088 seats/peak hour, or +32% core capacity (over and above the +10.7% capacity increase in Caltrain's FTA application).
The devil is of course in the details: changing the Stadler car shell is not free at this late stage of design, and lengthening trains to eight cars isn't just a financial headache but brings about awkwardness with certain platforms that are shorter than they ought to be.

Nevertheless, if it comes down to an existential issue of project eligibility, seat count nitpickers can undoubtedly be satisfied, and to everyone's benefit, by making a few basic adjustments. When a project's core capacity metric can be tripled for just 7% extra cost, it's a clear indication that it isn't an illegitimate fraud. Core capacity seat math either isn't an issue, or it can easily be resolved.

The Big Picture

With the delay of a federal grant long planned for Caltrain modernization, there is fear and uncertainty on the peninsula rail corridor. Everything about the project is being put back into question by voices on all sides of the issue. In times like these, it helps to step back and look at the big picture. The big picture has not changed since 2008, and there is a logical flow to it that remains true regardless of the funding situation.

A requirement flow diagram shows a hierarchy of requirements, things that are needed or wanted, and how they relate to each other. The way to read it is to follow along the connectors between boxes. When reading downward, the next box down answers HOW the previous box is to be achieved. When reading upward, the next box up answers WHY the next box is necessary. A simple and intuitive example is provided at right.

Next, we move on to a more complicated diagram that represents the blended system in general, including the Caltrain modernization project. The derived attributes at the ends of the requirement tree are highlighted in green.  If you delete any of the green boxes, all of the boxes that depend on it above are negatively affected.

For example, if you delete level boarding, then you can't reduce station dwell times, which means you can't increase Caltrain average speeds enough to allow operating peak hour traffic, which in turn means the blended system won't work well, and HSR may need to build four tracks all the way.

For another example, if you delete train doors that work at the same height as HSR, then Caltrain can't share platforms with HSR, which means bigger stations and limited capacity at SF Transbay, so Caltrain won't be able to run all trains into the downtown core, which in turn will hurt Caltrain ridership and increase congestion on highway 101 and I-280.

(Click to expand to full size)
This is a useful way to think about the problem, and reveals three important ideas: (1) the mere lack of funding won't make the problem change or go away, (2) the technical approach pursued by Caltrain is sound, if only partially effective, and (3) hacking away the entire HSR side of the diagram doesn't fundamentally change the solution ultimately needed for Caltrain modernization.

Worth a Thousand Words

As Trump's FTA ponders whether to award a big chunk of federal money to make Caltrain great again, the agency itself is failing to promote in pictures what its modern fleet will look like. Visit caltrain.com or even the nascent but unadvertised calmodtrains.com, and you won't see any images of the new Stadler EMUs. We know they exist, and now might be a good time to splash them all over social media.

Here are two new renderings that emerged recently:

A new version of the original Palo Alto rendering, via Business Journal
Note the train now sports folding bridge plates on the high doors.
To be fair, Caltrain is really good at snark.

San Jose Done Right

Map of VTA's BART extension
San Jose is the tenth largest city in the U.S. (by population), with more people than San Francisco; the city achieves this statistical feat by encompassing 180 square miles.  Such a large and populous city surely deserves top-notch rail transit.  BART is widely viewed as top-notch rail transit, which is why the city and VTA (Santa Clara County's transportation authority) have made extending BART through San Jose their very top priority.

Actual expenditures from VTA
Measure A (2000) sales tax, 2015
So overwhelming is the priority for BART that VTA re-programmed the revenue from a half-cent transit sales tax (Measure A) passed back in 2000 primarily to the BART extension, breaking a promise made to voters that a significant portion would fund Caltrain electrification.  The actual expenditures through 2015 are shown in the diagram at left; money spent on the BART extension is shown in blue, and money spent on Caltrain in red.

As can be readily observed, the Measure A money is nearly gone, and the BART tunnel through San Jose is not even started.  That's why another half-cent transportation sales tax Measure B was passed in Santa Clara County in November 2016 to raise a further $6 billion through the year 2047.  Exactly like 2000 Measure A, 2016 Measure B promises lots of funding for Caltrain, an ample 16% slice that includes grade separations ($700M) and capacity improvements ($314M).  The small print, however, allows the VTA board to re-program the funding as it sees fit, adapting spending to "unforeseen" circumstances such as, perish the thought, an over-budget BART extension.

With San Jose and VTA suffering from a severe case of BART tunnel vision, it's important to take a more holistic view of what it means to provide the residents and workers of San Jose with a top-notch rail transit network.

San Jose Pan-Galactic Inter-Dimensional Station

San Jose planners will insist that creating a network is their highest priority, and to that effect, their Diridon Station Area Plan seeks to establish a new "Grand Central of the West," as described in Section 2.5 of the plan:
San José Diridon Station will be the best connected transportation hub on the West Coast with the convergence of virtually every mode of public transportation. Activity will increase dramatically with the addition of high speed rail and the extension of Bay Area Rapid Transit (BART) to Diridon station, combined with significant growth by current intercity rail, commuter rail, light rail and bus operators. These new services and growth in demand will create the need for a significant expansion of the existing station. 
This ambitious station development plan rests on two fundamental but unstated assumptions:
  1. Caltrain, ACE and Amtrak will continue to operate Diridon station as a terminus, where out of service trains are parked for extended layover periods, wasting valuable platform space as train storage.
     
  2. As a result, high-speed rail will not fit within the ground-level footprint of the station, and will most likely require an entirely new elevated facility built over the existing station.

Ridership assumptions for Diridon
These two assumptions are firmly rooted in the ambitious plans of numerous rail transit agencies that prefer to avoid stepping on each other's toes.  Each agency specifies its future needs, San Jose consultants unquestioningly tally up the numbers (see figure at right), and end up prescribing a framework that demands a massive station complex to support a nearly ten-fold increase in ridership over the next twenty years.

Caltrain and high-speed rail consultants have conducted a sophisticated simulation study known as an "operational conflict analysis" that predicted an intolerable traffic jam, with peak-hour delays of nearly an hour.

The Diridon Station Area Plan and the Caltrain / HSR operational analyses are flawed for having failed to examine and question the assumptions on which they are built.  Yes, the station has enormous potential to become a thriving transportation hub, but that is precisely what makes it a very bad place to park out of service trains. Parking or laying over trains at a station platform is the railroad equivalent of parking an empty truck in the middle of a bustling loading zone, and then concluding that the loading zone fails to function adequately and must be expanded.

Trains need to hustle in and hustle out without occupying enormously valuable platform tracks. As will become clear, the simple practice of not parking trains in the worst place to park trains enables a far more efficient and affordable at-grade station configuration for San Jose that provides the same great network effect and transportation benefits for the heart of Silicon Valley, saving enormous sums that can be re-invested to achieve a much better outcome for riders and taxpayers.

Here's San Jose done right:

1) Extend Caltrain through San Jose

Falling short: census data for the Caltrain corridor in San Jose,
overlaid with Caltrain service levels for April 2017.
Viewed as a line on a map, Caltrain already runs through San Jose and beyond, with Gilroy service having started back in 1992. San Jose Diridon station (served by 92 trains/weekday) isn't a natural terminus; south of it, there are three additional stops located within San Jose city limits: Tamien (dropping from 40 to 34 trains/weekday in April 2017), Capitol (6 trains/weekday) and Blossom Hill (6 trains/weekday). Service between Diridon and Tamien is timetabled at 7 minutes, which makes for an average speed of 15 mph, and average speeds south of there hover around 30 mph. The abysmal service south of Diridon station lacks two important attributes of top-notch rail transit: speed and frequency. That's why it's fair to say that despite that line on the map, Caltrain has yet to be extended through San Jose. It's time to do it properly.

One challenge is jurisdictional, with Union Pacific owning the tracks south of milepost 52 and VTA currently holding the rights for only ten daily round trips. However, UPRR does not make intensive use of these tracks, and as a profit-making enterprise would likely be receptive to an outright transfer of ownership while retaining trackage rights to continue operating its Coast Subdivision freight service as before. This would simply extend the existing arrangement between CP Coast (milepost 44.7) and CP Lick (milepost 51.6), where the Caltrain owns the right of way and dispatches the track, southwards to CP Coyote (milepost 59.9).

Another challenge is institutional, with VTA having a vested interest in making commuters use the Santa Teresa branch of its light rail network. The Caltrain San Jose extension would parallel this line, possibly cannibalizing some of its ridership.

Built-up areas shown in black on a map
by the DLR Earth Observation Center
(Global Urban Footprint).  Tamien,
Capitol and Blossom Hill are shown
disconnected, as they are today.
Demographically, the southern half of San Jose is a rich but poorly tapped source of commuter ridership, with dense residential neighborhoods surrounding the corridor. More than 100,000 people live within two miles of the Tamien and Capitol stops, and 75,000 people live within two miles of the Blossom Hill stop. Census data argues strongly for locating the Caltrain terminus at Blossom Hill, with an electrified train storage yard / layover facility in this large vacant space [UPDATE: that large vacant space seems to be spoken for, so look for other unbuilt spaces in map at left], a far better place to park out of service trains than in the middle of San Jose Diridon. ACE and Amtrak trains could be turned at the existing Tamien layover facility.

Turning all Caltrain service at Blossom Hill would improve service for hundreds of thousands of San Jose residents and workers, at some increase in capital cost (to electrify) and operating cost (12 minute longer runs). On the other hand, it would greatly reduce Caltrain's requirement for tracks and platforms at Diridon station. Caltrain would operate through the San Jose Diridon station much like it does at the Palo Alto University Avenue station, using just two tracks and two platform faces. If that seems hard to imagine, remember that Palo Alto has almost 60% more ridership than San Jose Diridon; any perceived need for all those tracks and platforms at Diridon, and the profoundly mistaken notion of a "South Terminal", arises from existing jurisdictional boundaries and Caltrain's unhealthy habit of parking trains in the worst possible place to park trains.

2) Build high-speed rail at grade.

Thousands of cubic yards of concrete,
zero marginal transportation benefit
With Caltrain's San Jose footprint shrunk to just two platform faces, and with HSR's recent decision to shrink platform length to just 800 feet, it becomes feasible to operate the San Jose HSR service entirely within the existing at-grade footprint of the station, without the need for expensive new elevated or tunneled infrastructure. Two of the existing platforms are already over 1200 feet long and could be converted for HSR use. Just as in San Francisco Transbay, these platforms could be shared with Caltrain, taking advantage of Caltrain's new dual-boarding-height trains and leading to even more efficient utilization of the existing station footprint.

Operationally, HSR would have to quit the same nasty habit of parking trains in the worst possible place to park trains.  Trains would have to layover somewhere north of Diridon, or continue onto the peninsula rail corridor.  There is no operational need for longer station dwell times than two or three minutes within the Diridon complex: get in, board and/or alight passengers, and most promptly and importantly, get out. Go layover somewhere else than the bustling city center.

Building everything at-grade would save about a billion dollars (by foregoing about $250M for elevated approach tracks, $500M for the elevated Diridon station complex itself, and $500M for the "iconic" but entirely avoidable viaduct to cross the 87/280 freeway interchange to the south). An added benefit of the at-grade approach to San Jose is higher speeds and lower trip times. The extremely tight 1000-foot curve radius that connects Diridon to an "iconic" viaduct saps the 'H' out of HSR by limiting trains to just 50 mph, while the existing curve through the Gardner neighborhood could be grade separated and operated at 65 mph.

Rather than cower in the shadow of a new "iconic" bridge proclaiming loudly that they are just a flyover neighborhood, residents of San Jose's Gardner district would gain a grade separation at Virginia Street, improving neighborhood access that has been so brutally cut off by the I-280 and SR-87 freeways, and eliminating the sound of railroad horns--even freight train horns.

3) End the BART extension at Diridon/Arena

As planned by VTA, the BART to San Jose Phase II project doesn't just take BART to San Jose, but takes BART beyond the San Jose Diridon/Arena station, veering north to parallel the Caltrain / HSR corridor for a redundant 2.5 miles, ending in Santa Clara.  While this configuration might have made sense long ago when BART harbored ambitions to "ring the Bay" by linking Millbrae and Santa Clara, the present state of affairs argues for a different solution.

From a transportation perspective, it makes no sense to spend ~$1.5 billion of scarce transit dollars (pro-rated from the $6 billion cost of the entire Phase II project) on a 9000-foot tunnel leading to a huge Santa Clara station complex just to provide a third way to ride between San Jose Diridon and Santa Clara, two locations already well-linked by Caltrain and VTA's 522 express bus.

BART maintenance yard at Las Plumas
Avenue in San Jose, an alternative
that was withdrawn in EIR process
The main argument against truncating the BART extension revolves around a new 69-acre maintenance facility planned at Newhall Yard in Santa Clara. BART argues that Santa Clara and downtown San Jose are too far away from the nearest existing maintenance and storage facility, BART's main Hayward Maintenance Complex, to be operated efficiently. The HMC is about 21 miles from Santa Clara, requiring long non-revenue runs to stage trains to/from the end of the San Jose extension.  While this is admittedly an operationally inefficient arrangement, BART appears to have no qualms operating Phase I (to Berryessa) out of the HMC, over a distance of 14 miles. Cutting back the 2.5 miles from Diridon/Arena to Santa Clara would place the end of the line less than 19 miles from HMC, not so much further from the HMC than Berryessa already is. The HMC itself is undergoing a major expansion, with storage space for an additional 250 BART cars environmentally cleared based on a purpose and need statement that invokes servicing the BART to San Jose extension. Even then, if the HMC Phase II expansion were to prove insufficient and if maintenance and storage demands were truly that dire, a small portion of the $1.5 billion cost avoidance of truncating Santa Clara could be reinvested to provide a new BART maintenance shop at Las Plumas Avenue, an alternative that was considered during the environmental process. Trains could also be stored overnight at Diridon/Arena, to avoid long non-revenue runs at the start and end of the day. The bottom line: the argument that a Newhall shop is a non-negotiable, vital component of the BART to Silicon Valley project is technically unfounded and rests on a stay-the-course-at-all-costs logic that fails to appreciate the opportunity costs of blowing $1.5 billion on a train parking lot.

Another argument against truncating the BART extension concerns a planned airport people mover that would link Santa Clara to the SJC terminals, tunneling under the runways. Using a small portion of the $1.5 billion savings of ending BART at Diridon/Arena, the people mover could run straight to Diridon station, without the need for tunneling under the runways, and connect not just with Caltrain and BART but directly with high-speed rail--seamlessly merging the airport and the train station.

4) Use Newhall Yard for HSR

As it turns out, there is a better use for Newhall Yard than BART storage and maintenance, namely, HSR storage and maintenance.

As previously mentioned, long non-revenue runs to stage trains to/from their terminus are operationally inefficient, but BART can get by because nobody else uses their tracks. If the HSR storage and maintenance yard were to be located in Brisbane, these non-revenue runs would consume scarce and valuable operating slots on the extremely constrained peninsula corridor "blended system," further compromising service quality for all rail passengers.

A better plan is to have only a small storage / layover yard in Brisbane, with a larger facility perfectly located just north of San Jose Diridon at Newhall Yard, which would allow a portion of the HSR service to originate / terminate in San Jose without gumming up the peninsula rail corridor. Recall the blended system will be limited to 4 trains per hour per direction unless long stretches of the peninsula corridor are expanded to four tracks, an idea that faces twin obstacles of funding and community opposition.

Organisation vor Elektronik vor Beton

In Germanic countries, there is a guiding principle in rail system design known as Organisation vor Elektronik vor Beton, or roughly, organization before systems before concrete. It gives the order of priorities for quickly and affordably increasing train traffic: first you re-plan your operations, and if that doesn't cut it you improve your technology, for example by using shorter signal blocks, and only as a last resort do you pour concrete.

What is about to happen in San Jose is the exact opposite: legions of consultants primarily from a civil engineering background are (surprise!) recommending a concrete-intensive solution to a problem that is ill-posed because it hasn't first been attacked from the standpoint of re-planning train operations. The entire edifice is built on the nasty habit of parking trains in the worst possible place you could think of to park trains.

The planners and engineers working on the future of the Diridon Station area need to be sent back to the drawing board with new operating assumptions:
  1. Turn all Caltrains at Blossom Hill, operating San Jose Diridon as just another intermediate stop
  2. Turn all legacy diesel trains (ACE, Amtrak) at Tamien, away from the bustle
  3. Turn all high-speed trains originating or terminating in San Jose at Newhall Yard
Thinking of San Jose as a terminal is misleading. The litmus test is really simple: if your timetable, operating plan or simulation has any train spending more than two minutes dwelling at a platform in the San Jose Diridon station, then it is probably flawed. Don't turn trains at the choke point of your system, so that we don't spend billions on fancy train parking with zero value to the traveling public and negative value to the taxpayer.

The Bay Area can ill afford transit mega-projects of low utility, such as the redundant BART segment beyond Diridon/Arena to Santa Clara, the giant HSR station in the sky, or more downtown train parking. The cost is outrageous, and the opportunity cost is shameful.

UPRR Leaves, Sort Of

Caltrain and Union Pacific have recently agreed on the terms of a deal for UPRR ceasing to operate freight trains on the peninsula, between Santa Clara (CP Coast) to San Francisco. This is not the end of freight, however. The Deal Terms Sheet (2MB PDF) outlines the process by which a smaller "Short Line" operator would take over the rights and obligations to continue serving rail freight customers on the peninsula. It also unravels a laundry list of contentious issues that pitted UP and Caltrain against each other. In summary, there are three phases to the deal:

  1. The agreement recently entered into by Caltrain and Union Pacific, stipulating that:
    • UP will start looking for a new short line freight service provider.
    • Caltrain will ensure that short line locomotives with freight PTC can operate throughout CBOSS territory, a condition described as "unconstrained interoperability," a great pretext for more CBOSS program blowouts
    • Caltrain will ensure that Caltrain rolling stock can operate on UP's freight PTC equipped Gilroy branch, or cease operating on the Gilroy branch.
    • Caltrain agrees to never electrify UP's Main Track 1 from CP Coast (Santa Clara) through San Jose to CP Lick (south of Tamien), the land under which Caltrain owns.
    • UP agrees not to object to the CPUC safety requirements (1.4 MB PDF) formally adopted on 10 November 2016 for Caltrain's electrification project.
    • UP allows Caltrain's SSF station reconfiguration project to proceed, trading some old yard tracks and a loading dock for $2 million plus a new Caltrain-funded freight yard track at Newhall in Santa Clara.
    • UP settles some old claims by Caltrain for track maintenance.
       
  2. In the coming months, 
    • UP will select a Short Line and obtain Caltrain's approval.
    • Caltrain will sign a new trackage rights agreement with the short line.
    • Caltrain will sign a new trackage rights agreement with UP that replaces the current trackage rights agreement, concerning the "South Terminal Area" around San Jose.
    • The Surface Transportation Board will hopefully approve the whole deal, which is the entry criterion into phase 3.
       
  3. Upon STB approval,
    • Caltrain will own the "common carrier" obligations and be on the hook legally and financially for abandonment of freight service, should that ever be contemplated.
    • The Short Line will own the common carrier obligations on the sidings and lead tracks not owned by Caltrain.
    • UP will transfer to Caltrain the rights for intercity passenger service north of CP Coast in Santa Clara, but not south of there.
    • UP will agree not to pursue legal action against the electrification project.
This agreement could open a tiny sliver of hope for building grade separations that are both cheaper and more community-friendly without stubborn opposition from UP. On the other hand, it gives no hope for relief from freight PTC interoperability, justifying additional costs that have not already been sunk in the bottomless pit that is CBOSS.
