The T started with a general warning around 8:30 a.m. that Fitchburg Line riders could expect delays "due to a combination of minor train defects, switch failure & Freight train," but now they're up to delays of 50 to 60 minutes, at least on one Boston-bound train.

Bad news for people heading to Fitchburg this holiday morning: The T canceled train 2403 out of North Station and, after first telling passengers, woopsies, go take an Uber or something, decided to dig up a shuttle bus for the long ride out to Wachusett. The T is also telling passengers who'd hoped to take 2406 out of Wachusett to Boston at 1:15 p.m. to expect to ride a bus instead.

Delays on the Providence Line yesterday are being repeated this morning, if not quite as astoundingly. An hour delay on a train out of Wickford Junction yesterday has found a shadow in today's 810 out of Providence, which developed some of those "mechanical problems" and was more than 30 minutes late.

Signal problems on the Worcester Line, meanwhile, mean delays of up to 40 minutes on trains between Auburndale and South Station.

Hannah McGoldrick lays it on the line:

Going on day 9 of 15-minute plus delays on the Framingham/Worcester line. This is absolutely unacceptable.

The MBTA reports it's closed the Newtonville station on the Worcester Line "until further notice" because of some problems with the stairs up to the street that require immediate attention. The T says riders should head to West Newton instead - but will provide a shuttle bus 20 minutes before a scheduled train arrival from Newtonville to West Newton for people who don't get word in time to make the switch.

MassDOT reports the board that runs the T agreed to spend $345 million to buy 80 new bi-level coaches from Hyundai-Rotem - which will increase capacity on the entire commuter-rail system by about 14,000 seats a day once they all roll out and replace more of the single-level coaches still in use.
