The Saturday New York Times looks at NYC Transit which is working very hard to provide this information in Manhattan and Brooklyn.
Subways future and subways past seemed to collide on a recent morning at the Jefferson Street station on the L line in Bushwick, Brooklyn. New electronic signs on the platforms showed how many minutes a person would have to wait until the next train: at this moment it was eight minutes for a Canarsie-bound train and four minutes for a Manhattan-bound train.
But the recorded female voice on the public address system that was supposed to work in tandem with the signs was showing signs of a breakdown: “Ladies and gentlemen, the next L, the next L ——,” it said over and over, like a scratchy recording.
I am bothered by the fact the T has the ability to do this but flat out refuses to implement it in Boston.
