A freight train derailed in southwest Baltimore on Sunday morning on the MARC Camden Line, blocking all tracks and likely causing delays and disruptions for thousands of MARC riders during Monday morning’s commute, according to the Maryland Transit Administration.

A CSX train with two locomotives and 118 freight cars derailed eight of its cars just south of Camden Station near Interstate 95 at about 10:15 a.m. Sunday, CSX officials said. The train was traveling northbound from Hamlet, N.C. to Selkirk, N.Y. No injuries were reported and no hazardous materials were involved, according to CSX.

The cause is under investigation.

MTA spokesman Terry Owens said the Camden MARC line likely will be impacted Monday morning, but officials are unsure how long the disruption will last. MTA officials hope to have a decision by 10:30 p.m., which will be posted on the MTA website.

If the tracks are not clear by morning, there will be no train service to Camden Station, but MTA officials hope to open at least one track to Camden, which would cause delays of 15 minutes to 30 minutes on the line.

Trains on the Camden line might run on an “S” schedule, usually reserved for holidays. In that case, only train numbers with an “S” will operate.

The MTA is working to establish bus service between the Dorsey and Camden stations, but passengers are advised to use light rail to Penn Station or to arrange for alternate transportation.
