Fryslân Spoarwei (Frisian Empire)

Fryslân Spoarwei (English: Frisia Railway), or FS, is the principal railway operator in the Frisian Federation. Its trains operate over the tracks of the Frisian national rail infrastructure, operated by GrandRail, which was split off from FS in 2004. Freight services, formerly operated by Hefftreinen are now part of the DB Fracht group since a merger in 2001.

FS handles 1.2 million passengers every day, with 5,000 scheduled trains.
