Starting March 1st, there is another cheap way to travel from Fredericksburg to DC and get out of the I-95 gridlock.
While the express lanes construction is underway, people with a validated VRE ticket can buy an Amtrak step-up ticket foronly three bucks. Then, any VRE rider that uses a station served by Amtrak can ride its' rail instead.
The discounted ticket is designed to reduce traffic and makes VRE train less crowded.
