The MTA is reducing service because the train cars have been breaking down this winter faster than crews can repair them.
This new reduced schedule means a ten percent less service during peak hours, a Sunday schedule on Saturdays and bus service along the Waterbury branch.
Why the reductions? A whopping 70% of the cars on this line are more than 40 years old and the recent severe weather has been taking its toll.
On any given day, more than 150 cars are out of service, officials say, causing last minute cancellations.
The MTA says the older cars weren't designed to withstand the severe cold and snow.
