Dorsey is a passenger rail station on the MARC Camden Line between Washington, DC and Baltimore's Camden Station. The station is located at Exit 7 on Maryland Route 100, a.k.a.; the Paul T. Pitcher Memorial Highway. It was built by MARC in 1996 as a replacement for a former Baltimore and Ohio Railroad station located next to a 14-foot-10-inch (4.52 m) clearance bridge over Maryland Route 103. The former B&O station site is now a condominium development.
