SJ Y6

Y6 was a series of diesel railcars operated by Statens Järnvägar (SJ) of Sweden. 378 motor cars and 321 trailers were delivered between 1953-61 by Hägglund & Söner, Svenska Järnvägsverkstäderna, Kalmar Mekaniska Verkstad and Eksjöverken. They were used throughout the unelectrified Swedish rail network during the 1950s to the 1980s. The electrical counterpart of the unit was the X16 and X17.

In addition to SJ, five units were sold to Göteborg-Särö Järnväg in 1954.

In 1981 five units were sold from SJ to the Norwegian State Railways, where they were designated NSB Class 89 and used on the Flekkefjord Line. In Sweden the units were replaced by the Y1 railcars in the 1980s.

One Y7 unit, 1212, was preserved in the UK in 1985, and is now operated by The International Railway Preservation Society. It has been returned to working order and following a move back to the Nene Valley Railway won the Railcar Associations Railcar of the Year Award 2012.

Variations

Y6 was the original version, delivered 1953-57 and in 251 copies. It has smaller and simpler seats, with five-abreast, totalling 53 places. They were built by Hägglunds, ASJ and Kalmar. The last one left service in 1983, but many were rebuilt as service cars for railway maintenance. Some are still (2008) used for that. 26 cars were also sold to Danish private railways.
