Train

More than 80 trains a day arrive at Washington, D.C.'s, Union Station. Amtrak's regular service runs from D.C. to New York in 3¼–3¾ hours and from D.C. to Boston in 7¾–8 hours. Acela, Amtrak's high-speed service, travels from D.C. to New York in 2¾–3 hours and from D.C. to Boston in 6½ hours, but can cost as much as a flight. Two commuter lines—Maryland Rail Commuter Service (MARC) and Virginia Railway Express (VRE)—run to the nearby suburbs. They're cheaper than Amtrak, but the VRE doesn't run on weekends or federal holidays. MARC's Penn Line does run on weekends, offering service to Baltimore for $7 each way.
