Swiss Federal Railways (German: Schweizerische Bundesbahnen, SBB; French: Chemins de fer f?d?raux suisses, CFF; Italian: Ferrovie federali svizzere, FFS) is the national railway company of Switzerland.

In Switzerland, SBB stands for Schweizerische Bundesbahnen, which translates to "Swiss Federal Railways" in German. Because Switzerland is a multilingual country, the national railway is officially known by three different sets of initials, which you will often see printed together as SBB CFF FFS. The "CFF" stands for Chemins de fer fédéraux suisses (French), and the "FFS" stands for Ferrovie federali svizzere (Italian). Founded in 1902, the SBB is world-renowned for its punctuality, efficiency, and the "clock-face" schedule where trains depart at the same minute every hour. It is the largest transport company in the country, managing a dense network of over 3,000 kilometers of track. An iconic symbol of the SBB is the Swiss Railway Clock, designed by Hans Hilfiker, which features a distinctive red second hand that pauses for 1.5 seconds at the top of every minute to ensure all station clocks across the entire national network remain perfectly synchronized with the central master clock.
