UPDATE: Rail service is also cancelled all day Tuesday. Only buses will run, and those will be on snow routes.
Bowing to the impact of continued snow and cold, the MBTA announced it would shut down all subway lines, trolleys and commuter rail at 7 p.m. Monday.
The shutdown comes on a day the T tried to eke through offering a reduced schedule. The Orange Line had planned bus replacement service starting at 10 a.m. through 3 p.m. from Sullivan to Oak Grove. But further problems caused them to institute bus replacement service from Forest Hills to Green. After one Red Line train had to be evacuated, the T said the closure could prevent other similar incidents:
"The accumulating snow is making it virtually impossible to keep rail lines operational. From a safety perspective, the MBTA is concerned about the risk of multiple disabled trains that would require evacuations on the tracks, potentially in the dark."
