A free shuttle bus runs between the station and the airport terminal at all hours.Although Penn Station is the Baltimore area's main intercity station, BWI Airport is a major station in its own right. It is Amtrak's sixth-busiest station in the Mid-Atlantic region, the third-busiest in the Baltimore-Washington corridor, and the 12th busiest nationwide. Located roughly halfway between Baltimore and Washington, it provides an additional option for Amtrak riders traveling to both cities.
