Update 4:35 p.m.
VRE has announced that flood restrictions have been lifted on both the Fredericksburg and Manassas lines so trains are allowed to move at normal speeds.
Virginia Railway Express riders will experience lengthy delays Wednesday afternoon as the commuter rail system must adhere to flash flood speed restrictions, VRE officials said.
CSX and Norfolk Southern have issued the flash flood warnings for the entire length of the Fredericksburg and Manassas lines, respectively. Fredericksburg riders on train 301 can expect 30 to 40 minute delays and Manassas riders on train 325 can expect about an hour delay, VRE officials said. It is unclear whether the restrictions will remain in place through the evening.
VRE officials said fast-moving water can cause severe damage to the tracks, so trains must reduce speed when the host railroads require them to.
VRE officials said they will update riders when they know how the restrictions will impact commutes.
