We don'tmake any predictions ourselves; this app is simply a UI sitting ontop of the MBTA's data. That said, their data is accurate enough togive you a general idea of the status of your train but notaccurate enough to set your watch by.For example, trains generally report themselves as on time with apredicted arrival/departure time equal to the scheduledarrival/departure time so long as the train is less than 5 minuteslate (the "5 minute rule"). Furthermore, if a train is delayedmid-trip it can take up to 15 minutes for the delay to propagatethrough the feeds. Lastly, the MBTA's data tends to operate on a1-2 minute delay; in fact, updated GPS locations only come throughin the feeds once every couple minutes.This app is NOT affiliated with the MBTA or MassDOT.
