Frozen switches caused MARC delays

November 29, 2021 | (WTOP's Dennis Foley reports.)

WASHINGTON — The Maryland Transit Administration is working to determine what caused switches to freeze, creating a headache for MARC rail commuters Wednesday morning.

“It’s not the kind of situation where you can forecast it, or you can tell, you just come upon it,” MTA spokesman Paul Shepard said on WTOP.

MARC officials hope to have normal service in the afternoon.

CSX gave the OK for trains to run as normal Tuesday evening, Shepard says.

The switches have heaters to avoid any freezing, and MTA is working to determine if they were malfunctioning or if they weren’t used, Shepard says.

On Wednesday morning, some MARC line trains ran an hour or two hours late because of frozen switches.

MARC’s Camden Line trains were significantly delayed due to frozen switches, which are owned and operated by CSX. The same problem was reported on the Brunswick Line.

The Camden Line saw delays in both directions.

The Brunswick Line’s delays were much as 90 minutes.

Also, the Penn Line’s Train 404 from Union Station was canceled.

The D.C. area saw single-digit temperatures early Wednesday morning after seeing several days of below-freezing conditions.
