MBTA Commuter Rail Tracker provides experienced Boston commuters with as much information as possible about the location and status of their trains. This app is designed for seasoned commuters who are already familiar with their line schedule. • Near real-time location information (next stop, current stop, GPS location, predicted arrival time, and vehicle speed). Please see the note below regarding accuracy. • Boarding statuses with track and coach number displayed next to each trip, as well as a dedicated "Departures" view to see the entire departures board for North & South Station. • "Late" status when the MBTA predicts that a train will arrive later than the scheduled time - even before a delay announcement is made. • View historical coach numbers, boarding tracks, and average on time percentages for your train. • Crowd-sourced data through the "Passenger Reports" feature. Is a prediction wrong? Train delayed mid-trip? Wondering if your train is standing room only? Discuss through the "Reports" button next to each trip. • Full schedule view with predicted arrival times for each stop on your trip. • View the exact location of your train on a map. • Service alerts view. • Easy access to the @MBTA_CR Twitter account where status updates and additional info is usually posted in the event of a delay. • Clean, user-friendly, and ad-free interface. --- How accurate is this app? --- Data is sourced directly from the MBTA's real-time feeds which is collected using PTIS equipment installed on the trains. We don't make any predictions ourselves; this app is simply a UI sitting on top of the MBTA's data. That said, their data is accurate enough to give you a general idea of the status of your train but not accurate enough to set your watch by. For example, trains generally report themselves as on time with a predicted arrival/departure time equal to the scheduled arrival/departure time so long as the train is less than 5 minutes late (the "5 minute rule"). Furthermore, if a train is delayed mid-trip it can take up to 15 minutes for the delay to propagate through the feeds. Lastly, the MBTA's data tends to operate on a 1-2 minute delay; in fact, updated GPS locations only come through in the feeds once every couple minutes. This app is NOT affiliated with the MBTA or MassDOT. Follow us on Twitter at @MBTARailTracker for updates.



  • Useful

    Very useful to find where your train is while waiting at the staton
  • Saving my morning, every day

    I use this app together with the Alexa BostonRail skill and it saved me so many hours of waiting on the platform for trains that are late. Even when the MBTA screws up the data feeds, the passenger report help to gauge the real position of a train. One of the most used apps on my phone!
  • Why no information on train 500 from Worcester

    By louberghini
    All of a sudden the information stoped.
  • Bad update

    By meggermeter
    App was great until recent update. Now it doesn’t show early trains.
  • Update not working

    By Pandaman1988
    This was a wonderful app but the new update is causing my app to not show any trains. Please fix
  • Pretty great app

    By Groookyer
    Thanks for this useful app!! Seems bug-free. I wish that when I drill down to train history that I could see user’s message history too....Just for fun.
  • Thought this was a saving grace

    By Wildman93
    But I was wrong. Of course during yet another frigid day in Boston, I was counting on the app to keep me from freezing very long. The Franklin/495 listing showed it had problems reporting. Yet two stops just ahead of mine were light grey as opposed to dark. Although no times were shown “scheduled” or “predicted”. The comments are conflicting as someone mentioned they were in an ice box and the train hadn’t arrived in Norfolk while another wrote a few minutes later that it just left. So hedging this information I headed for the train and it was pulling out just as I arrived. And still the app shows no indication of movement. So glad I paid for this. The developers should offer a make good if they ever want to regain my trust.
  • Good

    Provides good info. Text could be a bit larger.
  • Trains

    By Geronimo1965
    This year the train schedule has been a bit better than last year. I am a frequent user on occasion there is a hiccup due to Mecanical/emergencies my suggestion would be to post this ahead of time on the platform monitors so that we are kept to b the loop. Another suggestion would be to send alerts to our mobile phones if we have the app.
  • The best train app

    By 'Ru
    This was already my favorite commuter rail app because it has all the info I need (train times, delays, alerts, maps, marking favorite trains, reports/comments from users), and version 2.0 made even more improvements. The app is very noticeably snappier, and remembering the last line you viewed when you reopen the app is super helpful. Well done!
