Question: Main Line Method is a band from Downingtown, Pennsylvania, the name comes from the Philadelphia area "Main Line", known simply as the Main Line, is an informally delineated historical and social region of suburban Philadelphia, in which state?
Context: The Philadelphia Main Line, known simply as the Main Line, is an informally delineated historical and social region of suburban Philadelphia, Pennsylvania.  Lying along the former Pennsylvania Railroad's once prestigious Main Line, it runs northwest from downtown Philadelphia parallel to Lancaster Avenue (US Route 30). Main Line Method is a band from Downingtown, Pennsylvania.  The band consists of just Tim Develin and Henry Sappey, although most of their works are multi-instrument pieces (Tim playing drums and bass, Henry playing rhythm and lead guitars).  The name comes from the Philadelphia area "Main Line" which is comprised of many suburbs to Philadelphia, such as Wayne, Malvern, and Tim's birthplace, Bryn Mawr. The Lehigh Division is a major freight low grade rail line owned and operated by the Reading Blue Mountain and Northern Railroad in the U.S. state of Pennsylvania that runs from Lehighton, Pennsylvania to Dupont, Pennsylvania, it originally ran from Lehighton to Mehoopany, Pennsylvania.  The Lehigh Division was formed in 1993 by Conrail from the Lehigh Line, officially the former main line of the Lehigh Valley Railroad (LVRR) that has absorbed former Central Railroad of New Jersey (CNJ) main line trackage and former Lehigh and Susquehanna Railroad (L&S) main line trackage into its system under Conrail; the Lehigh Line today is owned by the Norfolk Southern Railway and connects to the Lehigh Division at Lehighton. Main Line Broadcasting was an American media company, based in Philadelphia, Pennsylvania.  At its peak, Main Line Broadcasting owned 19 radio stations in four markets in the United States.  The company was founded by Dan Savadove, and was most recently run by CEO Marc Guralnick.  Main Line was backed by the Arlington Capital Group, a private equity company. Pennsylvania Canal "(or sometimes Pennsylvania Canal system)" refers generally to a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts.  The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items.  It should be understood the "first use of any railway" in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed Right of ways mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania.  Enacted before Railroads gestated during their infancy, the focus of the act was to create through building a canal system, the capability to ship heavy or bulk goods and connect Philadelphia to Pittsburgh—and "more importantly"—and "beyond" to the "new growth markets" in the developing territories reached by the Ohio River now called the midwest.  Later, when updated in 1837 to reflect the experience of twelve years of toddler-railways, the term was also applied to railroads and new canals to be added to the state transportation system.  As a crowning achievement, the Main Line of Public Works and the Pennsylvania Canal system topped 2100 ft in elevation by erecting the Allegheny Portage Railroad, which used a system of five inclines and five planes on each side of the Eastern Continental Divide at Cresson Pass in Cambria County to actually haul wheeled flat cars, which had halved canal boats placed on them, up and over the Allegheny Front and connect Pittsburgh to the Susquehanna.  When finished in 1834 the trip from Philadelphia to Pittsburgh could be made in 3–5 days, weather conditions depending. The New Holland Secondary is a rail line that runs from Lancaster, Pennsylvania to New Holland, Pennsylvania and is owned and operated by Norfolk Southern Railway.  It is 12 miles long, single tracked and originally ran from Lancaster to Downingtown, Pennsylvania, but all track between New Holland and Downingtown has since been abandoned.  The line branches off of track 4 of the Amtrak owned Philadelphia to Harrisburg Main Line (originally part of the Main Line of the Pennsylvania Railroad) at Cork Interlocking, milepost 67.0 in Lancaster. The Main Line of the Pennsylvania Railroad was a rail line in the U.S. state of Pennsylvania, connecting Philadelphia with Pittsburgh via Harrisburg.  The rail line was split into two rail lines and now all of its right of way is now a cross-state corridor, composed of Amtrak's Philadelphia to Harrisburg Main Line (includes SEPTA's Paoli/Thorndale Line service) and the Norfolk Southern Railway's Pittsburgh Line. The Varanasi–Jaunpur-Faizabad-Lucknow line (also known as Varanasi-Lucknow Via Faizabad Main line) is a railway line connecting Varanasi and Lucknow, both in the Indian state of Uttar Pradesh.  The main line was subsequently extended to Bareilly, Moradabad and Saharanpur and the entire line was thought of as the "main line" of Oudh and Rohilkhand Railway.  An important branch line, the Allahabad-Faizabad line, which meets the main line almost at right angles, is included here.  The main line is under the administrative jurisdiction of Northern Railway, a portion of the branch line is under the jurisdiction of North Central Railway. The Nankai Main Line (南海本線 , Nankai Honsen ) is one of the two main railway lines of Japanese private railway company Nankai Electric Railway, together with Kōya Line.  The route is from Namba Station in south downtown of Osaka to Wakayamashi Station in Wakayama via Sakai, Izumiōtsu, Kishiwada, Kaizuka, Izumisano, Sennan, Hannan and Misaki municipalities.  The proper name is with the company's name, "the Nankai Main Line", not simply "the Main Line" often seen in other Japanese private railways.  Lines of the Nankai Main Lane and the connecting lines excluded the Kōya Line and the Airport Line are named generically "the Nankai Line (南海線 , Nankai Sen ) ".  The line is shown with a pictogram of waves, or distinguished with blue from conifer or green Kōya Line. The Ninth Street Branch was an elevated railway line in Philadelphia, Pennsylvania.  It was operated by the Reading Company; ownership was split between the Reading and its subsidiary the Philadelphia, Germantown and Norristown Railroad.  It was a four-tracked main line beginning at the Reading Terminal, the Reading's terminus in Philadelphia, and extending north into the city to a junction with the Bethlehem Branch.  After the final bankruptcy of the Reading the line passed to Conrail and later SEPTA.  The portion south of the Temple University station was abandoned in 1984 with the opening of the Center City Commuter Connection and is now known as the Reading Viaduct; the portion north is now part of the SEPTA Main Line.
