The Red Line will run at reduced service levels for the Wednesday morning commute as the work of re-railing the car and removing the train that derailed Tuesday at JFK/UMass station continues into the early morning hours, officials said.

Travel on the Red Line is expected to be 20 minutes longer than usual, Lisa Battiston, a spokesperson for the MBTA, said in a statement.

Red Line trains will operate at reduced speeds while traveling through the area of JFK/UMass station, Battiston said.

Riders on the Braintree branch will need to switch trains at JFK/UMass station for service to South Station, the transit agency tweeted shortly before 8:30 p.m. Tuesday.


Riders on the Ashmont branch will not need to switch trains, the T said.

Additionally, the MBTA announced on Wednesday morning the Red Line will shut down for repairs after the morning commute. Shuttle buses will replace Red Line service in both directions between North Quincy and JFK/UMass for several hours beginning 11 a.m.

Passengers can also take the Middleborough/Lakeville, Kingston/Plymouth, Greenbush, and Fairmount commuter rail lines by showing a CharlieCard or CharlieTicket, the MBTA said.

”Additional Commuter Rail trains will be put into limited service between Braintree and South Station,” the MBTA said.

Commuter rail trains will leave Braintree at 6:20 a.m., 8 a.m., and 9:30 a.m., Quincy Center at 6:30 a.m., 8:10 a.m., and 9:37 a.m., and JFK/UMass at 6:50 a.m., 8:20 a.m., and 9:55 a.m., according to the MBTA.

Countdown clocks at all Red Line stations have been temporarily turned off to avoid displaying inaccurate predictions, Battiston said.

Unlike Tuesday, when heavy rain worsened the commute for thousands of passengers, the forecast for Wednesday is more promising.

The weather during the morning commute is expected to be sunny with no rain and temperatures in the 60s, according to the National Weather Service.
