Swiss Federal Railways (German: Schweizerische Bundesbahnen, SBB; French: Chemins de fer fédéraux suisses, CFF; Italian: Ferrovie federali svizzere, FFS) is the national railway company of Switzerland.
The company was founded in 1902 and is headquartered in Bern. It used to be a government institution, but since 1999 it has been a special stock corporation whose shares are held by the Swiss Confederation and the Swiss cantons. It is the largest rail and transport company of Switzerland; it operates on most standard gauge lines of the Swiss railway network. It also heavily collaborates with most other transport companies of the country, such as the BLS, one of its main competitors, or Südostbahn (SOB), to provide fully integrated timetables with cyclic schedules.
