The MBTA is getting $75 million from the Obama administration to improve the Fitchburg commuter rail line.
Federal Transit Administrator Peter Rogoff said the project will cut commute times.
"It's the slowest route in the whole MBTA system, and with the investments we're going to make, we're going to improve people's weekly commutes by more than an hour and a half, Rogoff said.
The Fitchburg line currently serves 10,000 commuters daily and is often plagued by delays.
