At its inception on May 1, 1971, Amtrak ran two through services on the line: the combined New York–Chicago "Broadway Limited" and New York–St. Louis "Spirit of St. Louis" (soon renamed "National Limited"), and the Pittsburgh–New York "Duquesne" (soon renamed "Keystone"). The former train stopped only at Lancaster and Paoli between Harrisburg and North Philadelphia; it was intended for long-distance travelers between the East Coast and the Midwest rather than local passengers. The "Duquesne"/"Keystone" had one additional stop at Coatesville and was intended for medium-distance intercity travel.
