MBTA begins rollout of long-awaited countdown signs

The MBTA will activate long-awaited countdown signs on Wednesday telling riders when the next trains will roll into South Station, the start of a pilot program that could be extended to all 51 Red, Orange, and Blue Line stations by the end of the year.

The arrival times, ticking down in one-minute increments, will appear on LED signs that have hung above platforms and in station lobbies since 2007 but that until now have displayed only the date, time, and announcements.
