TrainTrack

Stop staring
at the board.

Tap the train you're taking. TrainTrack watches NJ Transit's departure board for you and puts the track, the boarding call and every change on your lock screen, so you can wait anywhere but under the screens.

    Arrived at Trenton. It wraps up quietly a few minutes later.

The board, in your pocket.

Transfers

One change, both trains watched

Trips that need a transfer are planned as one itinerary. TrainTrack tracks the first train, and as soon as it departs it switches to the connecting train's track at the hub, with a realistic buffer for the walk. If the first train runs late enough to miss the connection, the app says so.

The fine print

Same data as the station board

Tracks and statuses come from NJ Transit's DepartureVision feed, the source behind the displays in the station. TrainTrack checks it about once a minute, so what you see can trail the station's own boards by up to two minutes. When the track hasn't been posted yet, the app says so rather than guessing.

TrainTrack covers NJ Transit trains and buses. Amtrak, PATH and light rail aren't included. It is an independent app and is not affiliated with or endorsed by NJ Transit.

Questions, bugs, ideas

Tap Feedback? in the app (or shake your phone on the screen in question) to send a note with a screenshot, or email support. Replies come from the person who built it.

I didn't get an alert.
Check that notifications are allowed for TrainTrack in iOS Settings, and that the alert in question is switched on in the app's settings. Alerts are sent by TrainTrack's server, so they arrive with the app closed and your phone locked. Leave-by alerts also need location access, since they depend on where you are.
The track showed up later than on the platform display.
The feed updates about once a minute and TrainTrack checks about once a minute, so a posting can take up to two minutes to reach you. That is the trade-off for a battery-friendly app.
Does it work for trains later today?
Yes. The live board covers roughly the next two hours; beyond that, trains come from today's timetable and pick up live track and status about 90 minutes before departure.
Where does my data go?
There are no accounts, no ads and no cross-app tracking. The app only sends what it needs to: station and train numbers to fetch the board, the trips you follow so the server can alert you, where you're starting from when you plan a trip from your location (never stored), and feedback when you choose to send it. The privacy policy is short and specific.
