For Trenton and Philadelphia, travel south from Princeton Junction toward Trenton. From Trenton, connections are available on SEPTA, Amtrak, and the River Line to Camden. Depending on your route, Philadelphia Airport or Center City Philadelphia may require another transfer.
The same route plan applies for many longer trips: Dinky to Princeton Junction first, then mainline rail or other public transport from there.
Schedule, Frequency, and Real-Time Status
The Princeton Dinky schedule is built around connections at Princeton Junction. The train operates seven days a week, generally from early morning to late night, and the running time is about five minutes in each direction.
| Service detail | Timings |
|---|---|
| Opening hours and starting time | Service begins in the early morning; exact opening times vary by day and should be checked before travel. |
| Working hours | Generally early morning to late night, seven days a week. |
| Frequency | Usually about two round trips per hour, or roughly every half hour, depending on Northeast Corridor connections. |
| Running time | About 5 minutes between Princeton and Princeton Junction. |
| Closing time and last train | Late-night service ends before all mainline service is finished, so check the last train and timings today if you are returning late. |
| Real-time status | Use the NJ TRANSIT App or Transit app for schedule today, train schedule updates, and service alerts. |
Departure times are not always on a perfectly even clock schedule. They are timed to match Northeast Corridor trains, which is why the app is the best place to check the timetable, route plan, and real-time status before you go.
If the Dinky cannot operate, buses may replace the train and keep service moving between Princeton and Princeton Junction.
Typical Travel Time and Service Pattern
The Dinky is a short shuttle with a very simple path: Princeton to Princeton Junction, then back again. There are no intermediate stations, and the trip takes about five minutes each way.
In normal service, the line runs about two round trips per hour. Late at night, pay close attention to the closing time and the last train, because a missed connection at Princeton Junction can leave you waiting without a Dinky back to campus.
The train normally operates with one- or two-car Arrow MU equipment. Because the route is only 2.7 mi (4.3 km), it is widely described as the shortest regularly scheduled commuter rail line in the United States.
Connections at Princeton Junction
Princeton Junction is the Dinky’s connection point to regional transportation in New Jersey and beyond. From this station, NJ TRANSIT Northeast Corridor trains run toward New York and Trenton, while Amtrak serves selected longer-distance routes.

Getting to and from Airports
The Dinky is often the final rail leg for airport trips to Princeton. Newark Liberty International Airport and Philadelphia International Airport are the most practical airport options mentioned for Princeton, while JFK and LaGuardia are possible but usually more complicated by public transport.
The basic route is simple: get to Princeton Junction by rail, then take the Dinky to Princeton. Taxis and rideshare services are available from the regional airports if you prefer a direct road option or are traveling with heavy luggage.
Newark Liberty International Airport
From Newark Liberty International Airport, take the AirTrain to Newark Airport Rail Station, then board an NJ TRANSIT Northeast Corridor train toward Trenton. Get off at Princeton Junction and transfer to the Dinky for the five-minute ride to Princeton Station.
For this trip, use NJ TRANSIT rather than Amtrak. The NJ TRANSIT App is the easiest way to check the schedule, buy a ticket, and confirm the correct route. Tickets can also be purchased at the airport before boarding.
The rail trip is generally about an hour and is often the simplest public transportation option between Newark and Princeton.
Other Regional Airport Options
Philadelphia International Airport is another option, but the public transport route has more steps. Travel from the airport to 30th Street Station, continue to Trenton, take NJ TRANSIT to Princeton Junction, and then transfer to the Dinky. From 30th Street Station, Amtrak to Princeton Junction may also be possible, followed by the Dinky or a taxi to campus.
From JFK, take the AirTrain to Jamaica, continue by Long Island Rail Road to New York Penn Station, then take NJ TRANSIT to Princeton Junction and transfer to the Dinky. From LaGuardia, taxi or rideshare service may be easier because rail access is less direct.
Trenton-Mercer Airport can work in specific cases, but it has limited destinations. For some travelers along the Northeast coastline, Amtrak to Trenton followed by another connection may be worth considering.
Parking, Bike Parking, and Last-Mile Access
The Dinky supports more than rail travel. Around Princeton Station, the transit plaza includes bike racks, short-term parking for Wawa patrons, a kiss-and-ride area, bus stops for NJ TRANSIT, TigerTransit, and freeB, plus taxi access.

Brief History
The Princeton Branch, locally known as the Dinky or the PJ&B, for Princeton Junction and Back, is widely described as the shortest scheduled commuter rail line in the United States. It runs 2.7 mi (4.3 km) between Princeton Junction and Princeton.
Service began in 1865 after local residents protested the railroad’s decision to move the main line away from Princeton. The original train took about 20 minutes each way, preserving rail access to the town.
Over time, the line became closely tied to Princeton University and the surrounding community. It carried passengers including Woodrow Wilson, Albert Einstein, and John Nash, appeared in the work of F. Scott Fitzgerald, and became part of local tradition.
The station location changed several times, including moves in 1917, 1918, and 2014. The branch was electrified in 1933, saw air-conditioned cars in 1975, and passed through different operators over the decades, including Penn Central, Conrail, the New Jersey Department of Transportation, and NJ TRANSIT.
In recent years, proposals to relocate the line or replace it with bus service have prompted public debate. For many residents and riders, the Dinky remains a familiar rail link and a living piece of Princeton history.
Future of the Princeton Dinky Corridor
NJ TRANSIT has narrowed its Princeton Transitway study to two remaining alternatives for the Dinky corridor: Alternative 1 and Alternative 4. The study is looking at how to improve transit between Princeton and Princeton Junction while deciding what role rail should play in the future.
Alternative 1 would replace the existing train with modern electric light rail running every 15 to 30 minutes. It would also add bus rapid transit over the same tracks, extending service through Princeton’s central business district and to the Princeton Shopping Center. Under this plan, bus rapid transit would run every 10 to 15 minutes, creating combined train-or-bus service every 6 to 10 minutes between Princeton and Princeton Junction.
This alternative would add new rail stations at Canal Pointe Boulevard and near Roszel Road, potential park-and-ride facilities for Princeton businesses, and a dedicated path for cyclists and pedestrians between Princeton and West Windsor. NJ TRANSIT estimates ridership could rise to about 2,175 daily passenger trips, with a capital cost of about US$101 million (USD $101 million).
Alternative 4 is essentially a no-build option. It would keep service operating with the existing aging trains and try to preserve the current system. Under this scenario, ridership could fall to around 750 daily passenger trips, with an estimated capital cost of about US$15 million (USD $15 million).
Other options have been removed from consideration. Alternative 2 would have created a separate busway alongside a light rail line, but it required substantial land acquisition and was considered too expensive. Alternative 3 would have used bus rapid transit only, with no rail service, but NJ TRANSIT said it was inadequate because Princeton residents strongly want to retain rail.
The future expansion debate now centers on whether to preserve the existing rail shuttle or move toward a mixed transitway model. The Dinky is not an urban tramway today, but the light rail proposal would move the corridor closer to a modern trams-style service pattern.
