Today’s commute largely went off without a hitch, in sharp contrast to Thursday, which was filled with transit delays thanks to the season’s coldest weather yet, officials said.
Out of 129 trains, only one, on the Green Line, experienced a mechanical problem this morning, said MBTA spokesman Joe Pesaturo, compared with 10 trains affected Thursday.
Beyond “an isolated signal issue at the North Quincy Station that had minimal impact on service,’’ the Red Line reported no delays this morning, Pesaturo said. There were no further issues at Central Square, either, where cold weather broke a rail Thursday.
The commuter rail system also had a good morning with 95 percent of the trains operating south of the city on time and a slightly smaller number — 92 percent — on time for northern communities, said Scott Farmelant, spokesman for the Massachusetts Bay Commuter Railway Co., which operates the commuter rail system under contract to the MBTA.
In contrast, on Thursday, the commuter rail on-time performance slipped to 78 percent, he said in an e-mail.
Farmelant said that many of the delays commuters faced on Thursday grew out of events outside of the commuter rail’s control. For example, an Amtrak train broke down outside South Station on, snarling train traffic out of the station that serves as the hub for two-thirds of the commuter rail system.
Similar problems happened today, but they were not as widespread.
This morning, five trains on the Providence, Worcester, and Fairmount lines were delayed due to a problem with an Amtrak train, he said. On the Fitchburg line, four inbound trans were delayed as much as 12 minutes by a failure of a signal on a track owned and operated by Pan Am Railways.
Lowell line riders on three trains were also delayed due to signal problems on another portion of the Pan Am Railways line, he said.
