Good MTA live station updates

MTA live subway map. Good for real time answers to which lines are running at a station and the headways for the next train arrivals.

One example of how this worked well is a fellow passenger missed a connection at a station. I was able to recommend which station to take next to get the required transfer, and skip a stop where that line wasnโ€™t running the right train at that moment.
