Amtrak's Broadway Limited
When Amtrak commenced nationwide operations on May 1, 1971, the Broadway Limited continued to use the all-PRR route, with a split at Harrisburg, Pennsylvania for trains to Washington, DC via Perryville, Maryland along the former Harrisburg, Portsmouth, Mount Joy and Lancaster Railroad, Columbia and Port Deposit Railway and Philadelphia, Baltimore and Washington Railroad until November 30, 1975. On November 12, 1990, due to Conrail's desire to abandon part of the former Pittsburgh, Fort Wayne and Chicago Railway in northwest Indiana, the line was rerouted to use the former Baltimore and Ohio Railroad west of Pittsburgh into Chicago. After the trips departing New York and Chicago on September 9, 1995, the Broadway Limited ended service, though it was briefly brought back as the Three Rivers. In 2005, the Three Rivers service was discontinued by Amtrak.
The Pennsylvanian, which operates as a daylight coach and snack-car service between New York Penn Station and Pittsburgh (subsidized by the Commonwealth of Pennsylvania), is today (2011) the only passenger train providing service west of Harrisburg along the former PRR mainline.
