Before Amtrak's creation on May 1, 1971, Penn Station served as the main Baltimore station for its original owner, the Pennsylvania Railroad (PRR), though passenger trains of the Western Maryland Railway also used Penn Station as well. It was also served by numerous PRR commuter trains to Washington, the ancestor of the MARC Penn Line. Well-known streamliners of other railroads, such as the Southern Railway's ""Southerner"" and all-Pullman ""Crescent Limited"", the Atlantic Coast Line's ""Champion"", and the Seaboard's ""Silver Meteor"", were operated by the PRR between New York and Washington, stopping at Baltimore's Penn Station to board passengers destined for southern points served by those railroads.
