service Norfolk Southern operates overnight freight service between the western junction of the Trenton Cutoff (a former Penn Central electrified "through-freight" line) and just west of Parkesburg via trackage rights, mainly supplying the ArcelorMittal steel plate manufacturing plant in Coatesville. Norfolk Southern also operates Enola Yard, a major freight classification yard near Harrisburg. Two other electrified through-freight lines, the Atglen and Susquehanna Branch (a.k.a. the Low-Grade Line) and the Philadelphia and Thorndale Branch, were abandoned by Conrail before its purchase by Norfolk Southern, with NS still maintaining the Low-Grade Line due to the catenary poles servicing the Keystone Corridor between Lancaster and Middletown, while the former has been looked at by the Delaware Valley Regional Planning Commission as a possible "Cross-County Metro" project connecting Thorndale with Trenton, New Jersey. Although there is electrified service on portions of the line all freight traffic is served using diesel locomotives. Former services The Broadway Limited, a train that operated between Chicago and New York, used the Keystone Corridor between Pittsburgh and Philadelphia and the Northeast Corridor between Philadelphia and New York. Originally a Pennsylvania Railroad train, this route was discontinued by Amtrak in 1995 but later restarted by the passenger rail company and renamed the Three Rivers. The Three Rivers was discontinued in 2005. (Amtrak's current Chicago-to-Washington, D.C. service, the Capitol Limited, uses the rail line west of Pittsburgh).
