6:43 A.M. Update:
VRE Fredericksburg Line train 304 is now 30 minutes late, while train 306 is following it and 15 minutes late.
VRE train 304 is delayed by 20 minutes due to equipment problems. That train will skip the Fredericksburg and Leland stations to reduce crowding, but train 306 (an eight-car train) will run 10 minutes behind train 304.
