Heat restrictions for MARC, VRE
The extreme heat Friday will cause delays for commuter rail passengers who ride the Fredricksburg Line on Virginia Railway Express and MARC passengers on the Brunswick and Camden lines.
VRE officials said CSX has issued heat orders for all Fredericksburg Line trains. Riders can expect delays of 10 to 15 minutes.Passengers can expected delays anywhere between 10 and 15 minutes, VRE spokesman Mark Roeber said.
The Maryland Transit Administration said CSX had also issued heat orders for the Brunswick and Camden lines. Delays on those lines may also run 10 to 15 minutes.
Trains must slow during extreme heat because the steel rails will expand, VRE officials have said. Although this expansion is taken into consideration during construction, 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.
