The Maryland Transit Administration plans to resume full service on MARC’s Brunswick Line Thursday, though the MTA warns that there could be some delays stemming from the cold.

Brunswick Line service was halted on Wednesday morning due to downed trees on the tracks. A train also struck a downed tree on Wednesday, as illustrated by this photo tweeted by Mary Anne Hitt:

The MTA said that there were four railcars and locomotives damaged on Wednesday morning. Crews repaired them to allow for normal service on Thursday. Still, delays of between five and 15 minutes are possible owing to the low temperatures, which could possibly freeze switches and signals, according to the rail agency.
