Heat delays for MARC, VRE -- again
The heat may have lessened today compared to earlier in the week, but passengers on commuter rail will still experience delays Thursday afternoon as offcials take precautions.
VRE officials said CSX has issued heat orders for all Fredericksburg Line trains. Riders can expect delays of 10 to 15 minutes, with the heaviest being near Fredericksburg. The Maryland Transit Administration said CSX had also issued heat orders for the Brunswick Line.
Trains must slow during extreme heat because the steel rails will expand, VRE officials said. There are occasions when the expansion can cause a "sun kink," or a shift in the track that causes a curve in an otherwise straight pair of rails.
