Where the region goes to work, and what Penn Station can carry
FRA’s Phase I plan could raise peak trans-Hudson service to 32 trains an hour inside the existing station. Census home-work records show a regional job market beyond Midtown that through-running could serve.
Penn can handle more trains within its existing footprint
FRA tested 86 operating scenarios and selected a hybrid plan built around three operating zones. Platform access, shorter dwell times, and fewer conflicting movements could raise peak-direction trans-Hudson throughput to 32 trains in the morning peak and 30 in the evening peak. The remaining question is how much passenger through-running the regional system can support reliably.
The operable starting point
Four commuter through trains per hour now have an operating case
Operating Concept 1 retains all 21 tracks, extends Platforms 1–3, adds vertical circulation, and clears obstructions from the platforms. Its three-zone service plan limits incompatible movements while preserving terminal operations where they remain useful.
FRA’s simulation found the concept workable with current arrival variability. Four commuter trains per hour in each direction would continue in passenger service through Penn, in addition to four Amtrak trains per hour in each direction.

The controlling constraint
Doubling through-running depends on reliability beyond the platform
Operating Concept 2 combines Platforms 5 and 6 into one wider platform and increases commuter through-running to eight trains per hour in each direction. Its working timetable reached the same 32-train morning peak-direction total as Concept 1.
The initial RTC simulation failed after current arrival variability and West Side Yard congestion were added. Higher through-running therefore depends on a service plan that reduces entry delays, relieves yard conflicts, or sends more trains through the regional network instead of reversing them at Penn or West Side Yard.
Concept 2 remains a capacity-neutral operating alternative until the required reliability measures are identified and demonstrated in simulation.
The regional market
Midtown remains the anchor inside a larger employment geography
The commuter-adjusted population within about 1.9 miles of Penn is the region’s largest concentration. Twelve additional study areas capture major centers in New York, New Jersey, and Connecticut. Their rail access varies: some have direct Penn service, some require a transfer or new service pattern, and some connect only through the wider network.
- Midtown commuter-adjusted population
- 1,363,130
- Net daytime change from commuting
- +895,680
- Commuter-adjusted to resident ratio
- 2.92
The twelve selected study areas contain 1,373,820 commuter-adjusted people under the specified hub boundaries. The total changes when the centers or radii change.
The figures measure residents and workplace populations inside defined hub areas. They establish the scale and direction of regional employment; they do not estimate rail ridership or prove that a particular branch pairing will operate.
Home and work
Employment links identify markets; operations determine which can become one-seat rides
LODES assigns covered jobs to a workplace block and a residential block. The largest links among the thirteen study areas run toward Midtown, while smaller cross-regional links connect centers outside Manhattan.
Primary jobs count each worker once using the job that provides the most earnings. All jobs can count one worker more than once.

The links that do not touch Midtown
Set Midtown aside and the remaining links are far smaller. The map redraws them on a larger scale so they can be read.
The records count jobs rather than observed trips. They contain no travel mode, departure time, route choice, or willingness to transfer. A through-running market becomes actionable only when its demand aligns with a feasible train path, compatible equipment, useful frequency, and balanced capacity in both directions.
The Phase II standard
The station design must preserve the operating choices that Phase II is testing
Concept 1 establishes an operable minimum of four commuter through trains per hour in each direction. Concept 2 establishes the higher target, but its reliability case remains unresolved. Structural work at Platforms 5 and 6, vertical circulation, columns, and track access must preserve both paths until the operating evidence supports a final service plan.

The decisive evidence
- Publish the train-by-train service plan and the branch pairings assigned to each through route.
- Release the RTC inputs and outputs, including dwell distributions, entry-delay variability, and recovery assumptions.
- Show how West Side Yard, Sunnyside Yard, platform turns, and outlying storage function under normal and disrupted service.
- Identify the fleet, power, clearance, crew, labor, and governance conditions required for each operating concept.
Sources and method
FRA’s 2026 Service Optimization Study supplies the operating concepts, train volumes, dwell assumptions, and simulation findings.
Home-work links use Census LODES 8.4 job records for 2023, primary jobs by default. The extract processed 12.74M block-to-block records and retained 2.20M in the selected counties. Commuter-adjusted population uses CTPP 2017–2021 resident and workplace estimates.
