Amid frigid temperatures, morning commute hampered on rail, Green and Red lines

Day three of frigid temperatures continued to tie up the morning commute, with cold weather splitting an air hose on one commuter rail train, officials said.

An inbound Providence/Stoughton commuter rail train could not leave the Providence station as scheduled at 7:35 a.m. today after a hose line split due to the cold weather, Massachusetts Bay Commuter Railroad Co. spokesman Scott Farmelant said.

He said the train sat at the station for 41 minutes; the train departed at 8:25 a.m., he said in an e-mail.

“When it’s cold, things tend to contract,” Farmelant said. “And once you find it, you replace it.”

At 9:52 a.m. today, the T reported that passengers on the Fitchburg/South Acton line “may experience significant delays” because of “major interruption in the signal system.’’

An outbound 8:35 a.m. Newburyport/Rockport Line train had mechanical failure just before 9 a.m., causing 15-minute delays

Another day of delays plagued some Green Line passengers, with a disabled outbound train at Arlington Station just before 9 a.m. Disabled trains at the C-Line’s Coolidge Corner stop and the D-Line’s Park Street platform were 15 minutes behind schedule just before 8 a.m.

All this despite 10 additional Green Line trains running for the morning commute, MBTA spokesman Joe Pesaturo said.

Red Line passengers also saw delays, with a disabled train at Quincy Center Station slowing the Braintree branch 20 to 25 minutes just before 9 a.m.

Northbound passengers on the Red Line also reported delays thanks to a disabled train

The officials would not say whether cold weather was a factor.

In Boston this morning, temperatures were in the double digits at 10 degrees at 9 a.m., though 16-mile-per-hour winds dropped wind chills to minus 6 degrees, the National Weather Service said.
