In the 1950s, SJ ordered more than 300 railbuses and trailers of the same type from different manufacturers. Railbus traffic ultimately saved traffic on many lines, as it was much cheaper and faster than running steam locomotives. This also meant that it was able to wipe out use of steam locomotives for passenger traffic in earnest.

These railbuses were equipped with a Scania diesel engine, referred to as a “straight 8” with turbocharger, and are known for their classic appearance and engine sound.

Y6 1109 arrived at the Swedish Railway Museum in the 1980s and is often used in trips between Gävle Central Station and the museum or the Train Hall.


Y6 is a designation (class) of the railbus type and means:

  • Y = Diesel-powered railbus
  • 6 = Type 6 within the Y family, which in this case means interior with low backrests and 53 seats
  • 1109 is the wagon’s individual number
