SEPTA lists 117 bus routes throughout Southeastern Pennsylvania, with most routes being within Philadelphia. Some of SEPTA's bus routes run 24 hours a day ("Night Owl" service), although most routes end by late night. SEPTA's bus service consists of its City Division routes within Philadelphia and Suburban Division routes in the suburbs. The Suburban Division consists of the Victory ("Red Arrow") District for routes in Chester, Delaware, and Montgomery Counties, and the Frontier District for buses to Montgomery and Bucks Counties. Other bus routes are its Regional Rail connector routes, the "Night Owl" bus service replacing the Market-Frankford and Broad Street subway lines during their closure, and other specialized services. SEPTA leases buses for third-party charter routes, and runs the charter buses for the School District of Philadelphia.
