Design the station around the trains. Not the other way around.
Amtrak will name a master developer for Penn Station within weeks. The decision will lock in the operational paradigm for decades. NJ TRANSIT OPRA records show the railroads already have the federal study's Phase 1 draft, while the final Phase 2 study is expected in Summer 2027. The case for through-running has to be made now, on the documents, before the contract is signed.
Penn Station is a terminal. The region needs a through-station.
The master developer will be selected after the railroads have received the federal Service Optimization Study Phase 1 draft, but before the final Phase 2 study is expected in Summer 2027. Whatever operating model the chosen consortium designs around becomes the operating model the next half-century of regional rail is built on. Changes after the contract is signed get expensive fast.
Penn Station was built as the southern terminus of the Pennsylvania Railroad. Most trains still arrive, dwell, and reverse direction. That paradigm produces three problems at once. Trainsets sit at platforms instead of moving people. Each railroad protects its own slots, which makes coordination across NJ Transit, LIRR, and Amtrak the exception rather than the rule. And the geography of the station forces conflicts at the interlockings that limit how many trains can actually move through, regardless of how many tracks the timetable shows.
This is not a station-design problem. It is an operating-model problem that has been allowed to look like a station-design problem for forty years.
- → Penn Station Access slipped to 2030 because the three operators could not coordinate the construction phasing.
- → The April 2026 Amtrak-MTA federal lawsuit over Acela testing access shows how brittle the current shared-use arrangement actually is.
- → The October 2024 feasibility study cited operational modeling against through-running. Amtrak FOIA responses and NJ TRANSIT OPRA records now present accounts that are difficult to reconcile.
Today, a passenger going from Montclair to Huntington requires two trains, a transfer at Penn, and roughly ninety minutes. Through-running collapses that into one train and roughly fifty. Multiply that across the dozens of cross-Hudson origin-destination pairs that sustained ridership across the region runs on, and you have the regional labor market the Gateway tunnels were built to serve.
What the operating models look like
Terminal operations require trains to reverse, which means crews change ends, dwells stretch, and the interlocking has to clear before the next train can enter. Conflicts at the throat of the station block other movements. The yellow zone shows where those conflicts compound.
Through-running uses the same tracks for continuous bidirectional movement. The platform turns the train in the time it takes for passengers to get on and off.
Through-running. The way every other major rail city does it.
Through-running means a train from New Jersey continues through Penn Station to Long Island, and a train from Long Island continues through Penn Station to New Jersey. The platform is a stop on a route, not the end of one. Every other major regional rail network in the world that has solved a comparable capacity problem has solved it this way. The Elizabeth Line in London. The RER in Paris. The S-Bahn in Berlin and Munich. The Stammstrecke in Zurich. None of them treat their central station as a terminus.
Penn Station has the track geometry to do this today. Tracks 5 through 21 already connect to both the Hudson tunnels to the west and the East River tunnels to the east. The 2021 MTA-WSP white paper confirmed the physical baseline. The question is whether the next operating contract is written around that capability or written around the assumption that Penn remains a terminal.
NJ TRANSIT OPRA records show the railroads have already received the Phase 1 draft report. Phase 2, the final phase of the FRA Service Optimization Study, is expected in Summer 2027. If through-running readiness is not in the RFP requirements, the design that gets built may assume terminal operations before the final study is complete.
The structurally important fact is that the October 2024 WSP/FXC feasibility study identified Sunnyside Yard in western Queens as the required location for a far-side turnback yard if through-running is the operating premise. That same Queens land is now the site of Mayor Mamdani's housing proposal. The geography is forcing a regional decision about how the same parcels get used. The answer to that decision should not be made by accident, by a developer working off a default operating assumption.
The terminal model: Trains arrive, dwell ten to fifteen minutes while passengers board and crews change ends, then reverse out. Each operator hoards capacity. A delay on one side wastes capacity on the other.
The through-running model: Trains stop briefly, exchange passengers, and continue. Penn becomes the middle of routes that connect the region. Service patterns are timetabled across the whole network, not just for trips into Manhattan.
Penn has 21 tracks. Tracks 5 through 21 already connect to both the Hudson and East River tunnels. The constraint is not the tracks. It is the dwell times, the platform widths, the vertical circulation, and the operating agreements between three railroads that currently behave as if they share a building, not a system.
- 17 through-tracks already exist. Tracks 5-21 support bidirectional operation today.
- Platform constraints are addressable. Wider platforms and "load and go" dwells reduce the bottleneck the 2024 study said was binding.
- Tunnel capacity is the real ceiling. Hudson at roughly 24 trains per hour plus East River at roughly 20 sets the system-wide cap. The station configuration determines how much of that ceiling actually translates into service.
- Unified dispatching is required. AC and DC traction differences are real but solvable. The harder problem is operating discipline across three agencies.
Every comparable city built tunnels to link its legacy terminal stations and operated them as a single through-running spine. None of them treated the original terminal as the endpoint of the system.
Thameslink and the Elizabeth Line
Cross-city tunnels connecting divided terminals. The Elizabeth Line moves more people through its central core than the entire LIRR system.
RER and S-Bahn
Suburban lines stitched through central tunnels. Direct trips across each metro region without the transfer penalty Penn imposes today.
The October 2024 study cited operational modeling. The public record now contains conflicting accounts of what modeling exists.
The case against through-running at Penn rests on a 2024 feasibility study commissioned by Amtrak, the MTA, and NJ TRANSIT. The study said operational modeling supported its conclusions. FOIA, FOIL, and OPRA records now show a gap between what Amtrak said it possessed, what Amtrak said was performed, and what FRA was asking NJ TRANSIT to release.
"The search did not reveal any simulations or modeling data in Amtrak's possession, and the dwell times were based on publicly available data."
"The work was led by MTA (and their consultant). We have no native files, operational models (because no simulations were performed) or calculation workbooks."
This week's NJ TRANSIT OPRA release adds a third layer. In November 2025, FRA officials asked NJ TRANSIT to release a "Penn Station-specific RTC model developed in coordination with MTA and Amtrak." Those records do not prove, by themselves, which agency holds each technical file or how each agency defined "simulation" in its FOIA responses. They do show that the public record is not yet complete.
- Amtrak appeal denial says its search found no simulations or modeling data in Amtrak's possession (Case 25-FOI-00443).
- FRA Director Lyle Leitelt emails NJ TRANSIT asking for the Penn Station RTC model.
- Amtrak's response in 26-FOI-00272 states explicitly: no simulations were performed.
- MTA grants the City Club's FOIL appeal. First production of underlying records due April 30. Full production June 4.
- NJ TRANSIT OPRA release confirms the FRA-MTA-Amtrak email chain on a Penn Station RTC model.
- NJ TRANSIT OPRA documents confirm the railroads have already received the Service Optimization Study Phase 1 draft report.
The technical case for southern expansion has rested on a study whose underlying modeling has not been publicly produced. Before a master developer signs a contract that will lock in operational assumptions for half a century, the documents underneath those assumptions deserve to be in the public record. The FOIL appeal grant means they soon will be.
What happens between now and the contract.
The procurement is on a federal timeline that compresses every step. Three consortia are bidding. The bid deadline is May 4. The board announcement follows shortly after. Construction is expected to begin by 2028. The federal study meant to evaluate the operating paradigm will not finish until after the developer is already designing.
Dates reflect the October 2025 RFLOI, the December 2025 shortlist announcement, the January 2026 finalist letter, and the publicly stated procurement schedule.

What you can do before the selection
The selection is days away. The questions below are designed to be used now, by the people who can ask them and have them count.
Federal and state officials
- Request a briefing from FRA and Amtrak on through-running readiness in the master developer RFP.
- Ask how the Phase 1 draft and forthcoming Phase 2 final study will be incorporated into the master developer contract.
- Tie future appropriations to public release of the technical assumptions underlying the contract.
- Ask for the operating-model documents that produced the 2024 feasibility study's conclusions.
Reporters and editors
- The selection-before-final-study mismatch is the structural story.
- The August 2025 Amtrak FOIA response, the February 2026 response, and the November 2025 FRA email asking for an RTC model are the documentary spine.
- The Penn Station Access 2030 slip is the case study in how three-agency coordination fails in practice.
- The April 23 Amtrak-MTA federal lawsuit is the present-day evidence that the current operating model is unstable.
Coalitions and organizations
- Sign on to letters demanding through-running readiness in the master developer RFP.
- Request the draft RFP and review the technical specs around platform widths, vertical circulation, and dwell-time assumptions.
- Prepare NEPA scoping comments now. The compressed timeline will not wait for organized response.
- Connect through-running explicitly to housing, climate, and labor-market goals you already work on.
Documents and analyses
Published material that supports the case made above. This list grows as records clear review.
Documents released through FOIA show Amtrak has paid the Regional Plan Association under contract to manage Build Gateway Now Coalition advocacy. RPA published a report on April 23, 2026 concluding that through-running would reduce capacity at Penn. A technical critique of that report, available below, evaluates its claims against international peer-system performance and the documentary record. Readers should weigh RPA's analysis with the funding relationship in mind.

The most frequent questions in policy conversations, media coverage, and community discussions. Answers here are informational, not the position of any agency.
The federal accelerated timeline mandates a construction start by 2028. The procurement schedule that produces that start has the master developer selected in mid-May 2026. NJ TRANSIT OPRA records show the railroads have already received the Phase 1 draft report, while Phase 2, the final phase of the study, is expected in Summer 2027. The selected developer could be designing around a default operating paradigm before the final study is complete.
This is the reason the operating requirements need to be in the RFP now, before the contract is signed. Once the developer is under contract on a "Base Scope" that assumes terminal operations, pivoting to through-running becomes a contract modification, with the cost and schedule implications that change orders bring.
No. Through-running is an operating model. It is about how trains use the tracks and platforms below the building, not about the building itself. The current Amtrak procurement focuses on renovating the existing footprint. The Block 780 expansion that would have required substantial real-estate disruption is not in the Base Scope.
Yes. The Hudson tunnels are essential to any operating plan. The question is what they connect to. Through-running treats the tunnels as the western half of a bidirectional spine that continues through the East River tunnels to Long Island. Terminal operations treat the tunnels as a feeder into a station where trains stop and reverse.
The 2015 Gateway Program technical memorandum projected 29 trains per hour eastbound capacity at the Gateway portal. The tunnels are designed for through-running volumes. Whether that capacity translates into regional service depends on the operating model the station is designed around.
The Penn Station South expansion that would have demolished Block 780 is not in the current procurement's Base Scope. Amtrak has paused that element of the prior plan and refocused the procurement on the existing footprint. The southern expansion has not been formally cancelled and may return depending on what the master developer proposes and what operational case the agencies make once the SOS produces findings.
The 2015 Gateway technical memorandum projected the southern expansion would yield 19 to 22 trains per hour as a stub-end terminal, less than what through-running can produce in the existing footprint with a Sunnyside Yards turnback.
The October 2024 WSP/FXC feasibility study identified Sunnyside Yard in western Queens as the required location for a far-side turnback yard if through-running is the operating premise. Mayor Mamdani's housing proposal is for the same site. The geography forces a regional decision: Sunnyside can be the operating-yard backbone of a through-running regional network, the housing site for tens of thousands of new units, or some carefully designed combination that makes both work.
That decision should not be made by accident, by a master developer working off the default assumption that Penn remains a terminal. It should be made deliberately, with full visibility into what the operating-yard footprint actually requires and what land remains available for housing.
FOIA-released documents show Amtrak has paid the Regional Plan Association under contract to manage Build Gateway Now Coalition advocacy and conduct public-facing campaigns supporting the Gateway program. RPA's CEO sits on the Amtrak board's advisory structures and shares trustees and senior staff with the Gateway Development Commission. RPA testified before the GDC without disclosing the funding relationship until FOIA productions made it part of the public record.
None of this disqualifies RPA's analysis. It is context readers deserve when weighing the technical conclusions of a paid advocate. The detailed critique of RPA's April 2026 report is in the resources section.
