Plan on roughly an hour to an hour and a half each way from the Princeton Junction station to New York Penn Station on NJ Transit's Northeast Corridor line, depending on the train you catch.
If you're relocating and weighing that commute, here's what's useful to know:
Express trains make a big difference. Some trains make fewer stops and get you into Penn noticeably faster. Look at the actual timetable for the hours you'd ride, not just the average.
Starting in downtown Princeton adds a step. A 2023 Daily Princetonian analysis found weekday trips from Princeton station, using the Dinky shuttle to the Junction, averaged about 1 hour 25 minutes to Penn Station. Starting at the Junction cuts out the Dinky leg.
Philadelphia is reachable too, but slower. Trips to Philadelphia mean transferring to SEPTA in Trenton, and that same analysis found weekday Philadelphia trips ran longer than New York trips.
Parking takes planning. Station lots are run by the West Windsor Parking Authority and NJ Transit. Ask about permits and daily parking before you count on driving to the train.
Where you live changes the commute. West Windsor and Plainsboro homes can be a short drive or bike ride to the station. From Lawrenceville, Pennington or Hopewell, you'll add a longer drive, or you might use the Trenton or Hamilton stations instead.
Hybrid schedules change the math. If you're in the city two or three days a week, a slightly longer commute may be worth a bigger yard or a different school district.
The best move is to ride the train once at your real commute time before you buy.
