The MTA is looking to help New Yorkers out by telling them when exactly their train is coming before they board it, giving them up to the minute reports on when it’s coming. Unfortunately though, it only works for the 1, 2, 3, 4, 5, 6 & 42nd Street Shuttle. The MTA would like to support other trains, but except for the L & 7, it would take “hundreds of millions of dollars & years of dedicated effort” for the rest of them to be upgraded for the app. Good news is that they are releasing the data behind the subway tracking, so companies like Google can plug it into their Maps app for better understanding of where your train is.
