The red line will run at reduced service levels for Wednesday morning commuting as the work to re-rail the car and the removal of the train that saved Tuesday at JFK / UMass station continues into the early morning, officials said.  Traveling on the red line is expected to be 20 minutes longer than usual, said Lisa Battiston, an MBTA spokesman, in a statement.
The Red Line trains will operate at reduced speeds as they travel through the JFK / UMass station area, Battiston said.

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

Commuter trains will leave Braintree at 6:20, 8 and 9:30, Quincy Center at 6:30, 8:10 and 9:37, and JFK / UMass at 6:50, 8:20 and 9:55, according to MBTA. 19659002] Countdown watches at all Red Line stations are temporarily turned off to avoid showing inaccurate predictions, Battiston says.
