An update and some clarification:
There are 4 tracks at East Brunswick, 2 main tracks and 2 yard leads, the 2 pairs of tracks are about 50ft. apart.
The 2 damaged tracks as pictured were #2 main track (normal eastbound track) and the South lead into Brunswick yard.
#1 main track and the north lead into the yard had debris and roadbed damage, but was able to be repaired within 24 hours.
#2 main track and the south yard lead were "patched" with rip-rap boulders and reopened with a 10mph slow order on Thursday p.m.
Keeping MARC's 20+ daily movements off this portion of the line gives CSX more flexibility to get their freights cleared up, along with the 2 daily Amtraks.
There was apparently 1 detour freight, a manifest run out of Curtis Bay yard and routed Hanover-Hagerstown-Cumberland.
This location is one of the most inaccessible in Brunswick yard with the only access through the yard or on the nearby C&O Canal towpath trail, which of course is now destroyed here. There is limited room for MOW to work.
This washout was caused by flash flooding on a 4-mile long creek, usually placid and about 8ft. wide.
Both the RR and canal culverts here were originally built in the 1830's, the RR's was rebuilt in the early 1900's because of yard expansion.
MARC has been able to run a limited service out of Point of Rocks using the Frederick maintenance/storage facility and the wye and station at Point of Rocks.
The Potomac River is scheduled to crest tomorrow afternoon at Point of Rocks at 3 ft. over flood stage, which should not affect the RR.
