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.



  • Trains

    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!
  • Good

    My wife and I Love this app! It provides the most accurate and up-to-date information in a format that easy to read and understand. We have other apps, but this is our primary! Keep up the good work!
  • Best commuter rail app around

    By Kyprioth
    I've tried several of the commuter rail apps, and this one is the best. Simple to use, info is clearly organized, and well maintained. Love the feature that shows likely track based on historical data. And the community input feature has saved me on bad weather days. Thanks for a great app!

    This app is super helpful and surprisingly accurate. If you ride the commuter rail you need this app. The passenger reports feature is so useful.

    Thank you for developing this app. It is the most reliable source for real time train status available. My fingers and toes thank you on this cold day.

  • Great app

    By DogeSam
    Super helpful and accurate. I used to use the free website but it was not very good and this app lets you write reports.
