The evening commute Friday was significantly better for travelers, and a bit warmer, compared with the frigid and delay-filled morning commute.
The MBTA suspended service between the Green Line E branch’s Brigham Circle and Heath Street stops in the evening for snow removal, according to the MBTA’s website.
The website also reported that commuters could expect delays on bus routes throughout the transit system, and on the commuter rail.
During the weekend, when a storm could leave a foot of additional snow in the area, the MBTA plans to use shuttle buses to move travelers while work crews remove snow in some areas on the Red Line and Orange Line.
The Red Line from JFK/UMass to Ashmont will be replaced by buses all day Saturday, and from JFK/UMass to Braintree all day Sunday, according to the MBTA website. The Orange Line from Oak Grove Station to Sullivan Station will also operate by buses all day Saturday.
The temperature in Boston on Friday hit 19 degrees, with a windchill of 7 degrees during the evening commute, compared with a minus-10 windchill during the morning commute, National Weather Service meteorologist William Babcock said.
Evening temperatures in the suburbs were even lower, hovering in the teens, with windchills in the single digits, Babcock said.
State Police Trooper Matthew Guarino said there were no major delays or accidents during the evening commute.
In the morning, however, passengers waited on platforms in ice-cold conditions as the MBTA confronted weather-related breakdowns on its trains.
On the B branch of the Green Line, severe delays were reported after a truck turned into the side of a trolley on South Street at 11:20 a.m., MBTA spokesman Joe Pesaturo said. No one was injured, but shuttles were replacing service between Boston College and Washington.
There were also delays on the Green Line D branch, on the Orange Line, the Red Line, and on various bus routes and commuter rail lines.
The MBTA has been struggling for the past week to recover from two major snowstorms and now must endure freezing temperatures.
Officials had warned Thursday afternoon there might be delays.
“The MBTA apologizes for the inconvenience while crews work to restore service to the levels customers expect and deserve,” the agency said in a statement.
Donna Sides, 58, of Acton said she has heard that apology too many times, yet has seen no improvements to MBTA service over the years.
Sides, a regular commuter on the Fitchburg Line, got on an express train at South Acton Station Friday morning, hoping for a quick commute to North Station.
“I had anticipated it would be a good day to take the train because it was Friday and a lot of people work from home, but the commuter rail is just so undependable,” Sides said.
Just two stops after she got on, Sides and other passengers were informed that their train would be standing by for at least 30 minutes because of a disabled train ahead of them at Concord Station.
A few minutes later, the power on the train went out, leaving the cars without heat. That’s when Sides decided she had enough. She called her husband to pick her up at Concord, and she spent the day working from home.
Sides said this was not the first time she was frustrated by delays on the commuter rail.
“It’s a real hassle,” she said. “I don’t see it getting better anytime soon.”
