A catenary wire snapped between the North Linthicum and Linthicum stations on the Maryland Transit Administration light rail, shutting down rail service from Patapsco, north of the break, to the southern ends of the line.
The MTA is taking passengers between stations by bus. Paulette Austrich, a spokeswoman for the MTA, said that the train is likely to remain out of service until Wednesday morning.
Due to flooding, the buses will not pick up or drop off passengers at two of the nine affected stops, Nursery Road and Linthicum, Austrich said.
Austrich said the cause of the problem was not known, and the wet weather may have played a role. To keep passengers who are forced to disembark dry, the MTA set up what it called a “comfort train” at the Patapsco station which riders can stand inside while waiting for a bus.
