BOSTON (CBS) – MassDOT is rolling out a new countdown clock system that will help keep ‘T’ commuters informed and on time.

The new signs, which are currently being tested in South Station, will help take the guess work out of your commute.

“Really for the first time our customers will not longer have to lean down the platform and look for that bright light from a train,” said Richard Davey, Transportation Secretary.

Davey said this project has been a year in the making and now commuters will know exactly how many minutes they have to wait.

So far the feedback has been positive.

“I think it’s a great improvement so people know roughly how long they are going to need to wait and I think that will reduce frustration and improve overall satisfaction with the MBTA,” said one ‘T’ rider.

The countdown clocks cost the State $800,000 and by the end of the year they will be on all Red, Orange, and Blue Line train platforms.
