MTA said a mudslide west of Brunswick and the threat of flooding at its Brunswick train depot has forced the closure of the 22-mile stretch of tracks.

"Additional infrastructure problems are likely given (Friday's) forecast for even more intense rain," said an update posted on MTA's website.

Service was already limited while CSX, which maintains the rails, repaired a track washout east of Brunswick.

Compounding a wet week of issues, MTA said MARC management ordered the relocation of many of its trains.

"The Brunswick storage yard is susceptible to flooding and given the rain we have had and the rain that is predicted, we must safeguard our locomotives and cars," read the MTA website.

MTA said if trains are left idle, they could be significantly damaged to the point of being unusable for six months or more.

Late Tuesday, a MARC train bound for Martinsburg went though high water near Point of Rocks. 80 people on board were moved to the top floor of the double-decker train for several hours until the water receded, but Frederick County firefighters told WUSA9 that no water entered the passenger area.
