TheSEPTA Main Line is the section of theSEPTA Regional Rail system from theZoo Interlocking inWest Philadelphia toLansdale Station inLansdale, Pennsylvania. The line is 26.25 miles (42.25 km) long, and serves all 13 SEPTA Regional Rail lines.^[1]

Service on the Main Line segment between Glenside andCenter City Philadelphia is given a special combined public timetable known as theGlenside Combined, allowing riders to see the schedules of all trains on the Main Line without having to look at multiple schedules. This is a partial legacy of SEPTA's formerdiametrical reorganization route number designations, which had theR1 Glenside designation for trains that terminated at the station, paired with theAirport Line. A contributing factor to the elimination of the R-number naming system came in the fact that few trains actually terminated there, instead continuing on to stations farther out.

As of 2024^[update], northbound trains on the Main Line that do not terminate at Glenside continue asLansdale/Doylestown Line,Warminster Line, orWest Trenton Line trains.^[2]

The Main Line was mostly built by theNorth Pennsylvania Railroad. However, the oldest section was part of thePhiladelphia, Germantown and Norristown Railroad (PG&N), the first railroad inPhiladelphia. The first section of it opened on June 7, 1832, from downtown toGermantown (now on the Chestnut Hill East Line). Later a new alignment was built toNorristown, leaving the old route from North Philadelphia to Germantown as a branch; this is now the Manayunk/Norristown Line. The PG&N south of Wayne Junction, theNinth Street Branch, is now part of the Main Line.

TheNorth Pennsylvania Railroad (North Penn) opened south ofGwynedd (north of Glenside) on July 2, 1855, and the continuation toLansdale (including the branch toDoylestown, now theLansdale/Doylestown Line) opened October 7. The short part of the Main Line from Wayne Junction northeast to north ofNewtown Junction was built as a connection to the PG&N at Wayne Junction.

On December 1, 1870, thePhiladelphia and Reading Railway (later theReading Company) leased the PG&N. The North Penn was leased May 1, 1879, placing the future "Reading side" of the SEPTA Main Line under Reading control. Electrification to Glenside, Hatboro, Lansdale, Doylestown and West Trenton was completed on July 26, 1931. In 1976Conrail took over the Reading, and in 1983 SEPTA gained control of the commuter operations. TheCenter City Commuter Connection was tied into the former Reading Ninth Street Branch on November 12, 1984, completing the SEPTA Main Line as it is defined today.

SEPTA activatedpositive train control on the Main Line from Glenside to Fern Rock on December 12, 2016 and from Fern Rock to 30th Street on January 9, 2017.^[3]

The term "Main Line" is also sometimes used on the SEPTA Regional Rail system to refer to thePaoli/Thorndale Line, which runs along the original main line of thePennsylvania Railroad, which is nowAmtrak'sPhiladelphia to Harrisburg Main Line.
