The Cheb–Oberkotzau railway is a railway line in Bavaria, Germany, and the Czech Republic which was built as a main line. It begins in Cheb and runs via Františkovy Lázně, Aš and Selb to Oberkotzau. The line was originally planned as a direct railway link between Cheb and Hof; but the plan was changed so that the existing Ludwig South-North Railway between Oberkotzau and Hof was shared. The section Aš–Selb-Plößberg was closed during the Cold War, but rebuilt and reopened in 2015.
