The 20-minute train: NJ Transit vs Amtrak under the Hudson

Here is a quietly useful fact: NJ Transit and Amtrak ride the same Northeast Corridor tracks and the same century-old North River Tunnels under the Hudson into New York Penn Station. From Newark Penn the trip is roughly 20 minutes either way. The difference is almost entirely price and seat.

NJ Transit: the value default

From the airport, one NJ Transit ticket — about $17.25 — bundles the AirTrain with the train to Penn Station. From Newark Penn it is a few dollars for the one stop. Frequent, unreserved, and the right answer for nearly everyone. Its only weak points are the AirTrain construction disruptions and the last mile from Penn.

Amtrak: the premium seat

Amtrak's Northeast Regional and Acela use the identical tunnels but charge a dynamic, reserved-seat fare that usually runs several times the NJ Transit price for the same one stop. Worth it in three cases: you already hold a rail pass; you want a guaranteed seat with heavy luggage; or you are connecting from a longer Amtrak journey and staying aboard. Note that not every Amtrak train stops at the airport station — many only call at Newark Penn.

The verdict

For a Newark→Manhattan hop, NJ Transit wins on value almost every time; Amtrak earns its premium only in those narrow cases. Both beat a car on a congested afternoon. Compare them head-to-head in the matrix, or read the NJ Transit and Amtrak entries.
