Capital Beltway was a railway station in Lanham, Maryland. It was built in 1970 by the Penn Central Transportation Company in partnership with the state of Maryland, the United States Department of Transportation (DOT), and Prince George's County. The station was located on the Northeast Corridor approximately 10 miles (16 km) north of Union Station in Washington, D.C. Its purpose was to provide a stop near the Capital Beltway ring-road for the new high-speed Metroliners. Amtrak used the station until 1983 when New Carrollton opened to the south.
