Amtrak vs NJ Transit at Penn Station
They share the same tracks but board in different buildings, charge dramatically different fares, and serve different kinds of trips. Here's how to know which operator you actually need — and what you give up if you pick the wrong one.
The Short Answer
Take Amtrak if...
- ✓Going beyond New Jersey (Philly, DC, Baltimore, Boston, Albany)
- ✓You want reserved seats, more space, café car, quiet car
- ✓You booked in advance for a good fare
- ✓On an intercity through-trip and Penn is one stop
Board at Moynihan Train Hall (8th Avenue)
Take NJ Transit if...
- ✓Traveling within New Jersey or NJ↔NYC Penn
- ✓You want the cheapest fare on a short trip
- ✓Daily commuting on a predictable schedule
- ✓Open seating is fine — no reservations needed
Board at the underground concourse (7th Avenue)

Side-by-Side Comparison
| Amtrak | NJ Transit | |
|---|---|---|
| Where you board at NYC Penn | Moynihan Train Hall (8th Avenue between 31st & 33rd Streets) | Underground concourse (7th Avenue entrance) |
| Primary routes | Northeast Corridor (Boston ↔ DC), Empire (NYC ↔ Albany ↔ Buffalo), long-distance trains, Keystone (Harrisburg via Philly) | NJ commuter rail — NEC, North Jersey Coast, Midtown Direct branches, Morris & Essex, Raritan Valley, Atlantic City |
| Typical fares | Demand-priced. Cheap when booked weeks ahead; expensive close to departure. Premium intercity service. | Fixed zone-based fares. Off-peak slightly cheaper than peak. Commuter-priced regardless of booking timing. |
| Distance / trip type | Intercity — Newark to Boston, Philly to NYC, DC to NYC, etc. | Commuter — anywhere in NJ to NYC Penn, plus some intra-NJ travel. |
| Reserved seats? | Yes (Acela, NER, Empire). Specific seats on some services. | No. Open seating, sit anywhere available. |
| Comfort | Roomier seats, café car, Quiet Car, power outlets at most seats, WiFi on most trains. | Commuter-bench seating, no café car, no Quiet Car, limited or no power outlets. |
| Onboard food & drink | Café car with snacks, sandwiches, coffee, beer & wine. | None. Bring your own. |
| Frequency at NYC Penn | Multiple per hour on the NEC daytime; less on other corridors. | Very frequent peak hours; reduced off-peak and overnight. |
| Late-night service | Limited overnight options on the NEC. | Late-night service runs on key corridors; reduced frequency. |
| Booking | Amtrak app or website. Book in advance for best fares. | NJT Mobile app, station kiosk, or ticket window. Same fare regardless of when you buy. |
Where the Two Overlap
Amtrak and NJ Transit share the Northeast Corridor through northern New Jersey, so for some specific trips you have a real choice. The most common is Newark Penn to NYC Penn — both operators run the route. The trade-offs:
- ▶Newark Penn → NYC Penn: NJ Transit roughly every 10–15 min during peak, ~20 min ride, commuter fare. Amtrak less frequent, ~15 min, several times the fare. NJT wins almost every time.
- ▶NYC Penn → Newark Liberty Airport station: Same logic — NJT is the default; Amtrak only when you're already on an Amtrak through-trip.
- ▶NYC Penn → Trenton: NJT runs the NEC line all the way to Trenton; Amtrak also stops at Trenton on through-trips. NJT is cheaper; Amtrak is slightly faster.
- ▶NYC Penn → Newark Airport (EWR): Both operators stop at Newark Liberty International Airport station. NJT's Rail Link ticket includes AirTrain in the fare; Amtrak does not.

Where They Don't Overlap
For many trips, only one operator works at all:
- ▶Beyond New Jersey (Philly, Baltimore, DC, Boston, Albany, points west): Amtrak only. NJ Transit doesn't leave NJ on the south side or run beyond Hoboken-area connections to the north.
- ▶NJ Transit's Morris & Essex, Raritan Valley, and other inner-NJ commuter lines: NJ Transit only — Amtrak doesn't run these.
- ▶Long-distance overnight trains (Crescent, Silver Star, Lake Shore Limited, etc.): Amtrak only.
- ▶Atlantic City Line, Bay Head, and other NJ coastal/inland branches: NJ Transit only.
How Fares Work — and Why They're So Different
Amtrak and NJ Transit use fundamentally different pricing models, and that explains most of the price difference for the same physical trip:
Amtrak: demand-priced
Amtrak fares scale with how full the train is and how far ahead you book. Booking 2+ weeks out for a quiet midday train can be dramatically cheaper than walking up for a Friday-evening Acela. Saver fares (with rebooking restrictions) are the cheapest tier. Same route, different prices day to day.
NJ Transit: zone-based and fixed
NJT fares are based on the zone pair you're traveling between, with off-peak slightly cheaper than peak. The price doesn't change based on demand or booking timing — a Newark Penn to NYC Penn ticket costs the same whether you buy it 2 weeks ahead or 2 minutes before the train. Monthly passes are available for daily commuters.
What this means in practice: for short shared routes (Newark to NYC), NJT is essentially always cheaper because Amtrak doesn't discount intercity fares to commuter levels. For longer routes where only Amtrak runs, advance booking is everything.
Common Mistakes to Avoid
✗ Going to Moynihan for NJ Transit
NJ Transit ticketing, departure boards, and primary boarding all happen at the underground concourse via the 7th Avenue entrance — not Moynihan. You can technically reach NJT platforms from Moynihan once your track posts, but you won't see NJT departure info or buy tickets there.
✗ Going to the underground for Amtrak
Amtrak ticketing, the Metropolitan Lounge, and most Amtrak boarding happen at Moynihan Train Hall on 8th Avenue. The underground concourse has limited Amtrak presence and no departure boards for most trains. Save time and head straight to Moynihan.
✗ Assuming the cheapest fare wins for short trips
For Newark to NYC and similar short hops, NJ Transit is almost always cheaper than Amtrak — even Amtrak's lowest Saver fare. But for longer trips (Philly to NYC, DC to NYC), advance-booked Amtrak NER can be competitive with combining commuter rail across multiple operators.
✗ Using an Amtrak ticket on NJ Transit during normal operation
Cross-honoring is only announced during declared major service disruptions. In normal operation, your Amtrak ticket isn't valid on NJT, and vice versa. Buy the right ticket for the train you actually intend to board.
✗ Booking Amtrak last-minute and being shocked by the price
Amtrak fares scale steeply with booking timing. Same-day walk-up routinely costs several times advance-booked. If you know your travel date, book early — the savings are real.
✗ Skipping NJ Transit's Rail Link ticket for the airport trip
The Rail Link ticket from NYC Penn to Newark Liberty International Airport station includes AirTrain Newark in a single fare. Buying the rail and AirTrain portions separately costs more. Amtrak does not have an equivalent combined ticket.
Frequently Asked Questions
Do Amtrak and NJ Transit ever share trains?
No — they're operationally separate. They share tracks at and around Penn Station, but trains are operated by one or the other. A conductor for one operator won't service the other's tickets except during cross-honoring.
What about LIRR? Where does it fit?
LIRR is a third operator at NYC Penn, serving Long Island. LIRR uses dedicated platforms on the east side of the underground station with its own ticketing. LIRR doesn't overlap meaningfully with NJ Transit or Amtrak in terms of routes.
If I'm going to Boston, is there ever a reason to choose anything other than Amtrak?
No. NJ Transit and other commuter operators don't run service that far north. Your only realistic rail option for NYC to Boston is Amtrak. The Acela vs Northeast Regional question is a different one.
Can I use a NJ Transit monthly pass on Amtrak?
No, except during declared cross-honoring during service disruptions. Monthly passes are operator-specific.
Does NJ Transit serve Newark Liberty Airport (EWR)?
Yes — NJ Transit Northeast Corridor and many other lines stop at Newark Liberty International Airport station. From there, AirTrain Newark connects to the terminals. The Rail Link ticket combines both legs.
Which operator runs the trains to Atlantic City?
NJ Transit, on the Atlantic City Line. Amtrak doesn't serve Atlantic City. Trains start at Philadelphia 30th Street, so from NYC Penn you'd transfer at 30th Street or take Amtrak to Philly and then NJT south.
