Manayunk/Norristown Line

The route originates from the Center City Rail tunnel, and the two-track line splits off from the "SEPTA Main Line" north of North Broad Station. It then goes through Philadelphia's East Falls and Manayunk neighborhoods and Conshohocken before reaching Norristown. At Norristown Transportation Center, commuters can transfer to regular SEPTA surface buses or the SEPTA Norristown High Speed Line to 69th Street Transportation Center. From Norristown Transportation Center, the electrified line follows the single track Stony Creek Branch to terminate at Elm Street, while the double tracked main line continues to Reading. The Reading main west of Norristown currently carries no passenger service, and is owned and operated by the Norfolk Southern Railway as its Harrisburg Line. Beyond the terminus of the Manayunk/Norristown Line at Elm Street, the Stony Creek Branch continues as a freight line operated by CSX Transportation and the Pennsylvania Northeastern Railroad to Lansdale, where it ends at a junction with SEPTA's Lansdale/Doylestown Line just south of Lansdale station.

As of 2019, most weekday Manayunk/Norristown Line trains terminate at 30th Street Station or continue to various destinations such as Elwyn on the Media/Elwyn Line and Marcus Hook or Wilmington on the Wilmington/Newark Line. Most weekend Manayunk/Norristown Line trains continue to Elwyn on the Media/Elwyn Line.[2]

The Manayunk/Norristown Line was the Reading Company's Norristown Branch from Philadelphia to Reading, Pennsylvania. Electrified service to Norristown and Chestnut Hill East began on February 5, 1933.[3] Steam (and later diesel)-operated intercity services continued to operate beyond Norristown. By the 1960s Budd Rail Diesel Cars handled most of the Reading's diesel services, although the Reading's EMD FP7 locomotives, displaced from the Crusader, saw regular use on the Philadelphia–Reading run.[4] SEPTA discontinued services beyond Norristown on July 26, 1981.[5]

Between 1984–2010 the route was designated R6 Norristown as part of SEPTA's diametrical reorganization of its lines. Manayunk/Norristown Line trains operated through the city center to the Ivy Ridge Line (later Cynwyd) on the ex-Pennsylvania side of the system.[6] The R-number naming system was dropped on July 25, 2010.[7]

Early in 2013, SEPTA began to undertake major operational improvements and physical rehabilitation on the Manayunk/Norristown Line. Central to this project is the replacement of the 80-year-old wayside automatic block signal system with one that displays only in the operating cab, and operates in both directions on both tracks, thereby allowing greater operational flexibility. Two new remotely controlled interlockings are being constructed to facilitate bidirectional operation, one at Miquon, the other in Norristown between the main station and the Ford Street crossing. An electrified storage track is also being constructed at Miquon to allow for temporary turnback of trains at that station, as the line is periodically subjected to flooding from the Schuylkill River around Spring Mill and Conshohocken. Ongoing replacement of the line's overhead catenary, most of which is 80 years old, will continue along with the signal replacement. Also occurring in conjunction with these projects are the replacement of crossties, renewal of grade crossing surfaces, and trimming of brush and trees alongside the right-of-way.[8] The entire program is scheduled for completion in fall 2015, tying in with the FRA-mandated nationwide implementation of Positive Train Control (PTC) on American railroads by the end of 2015.[9]

SEPTA activated PTC on the Manayunk/Norristown Line on August 15, 2016.[10]

On April 9, 2020, service on the line was suspended due to the COVID-19 pandemic,[11] though Temple University and North Broad stations were still being served by other rail services. Service resumed on June 28, 2020.[12]
