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 Norges Statsbaner of Norway, where they were designated NSB BM89 and used on Flekkefjordbanen. In Sweden the units were replaced by the Y1 railcars in the 1980s.
[edit] Variations
Y6 was the original version, delivered 1953-57 and in 251 copies. It has smaller and simpler seats, with five a breadth totalling 53 places. They were built by Hägglunds, ASJ and Kalmar. The last one left service in 1983, but many were rebuilt to service cars. 26 cars were also sold to Danish private railways.
Y7 has fewer and taller seats than the Y6, with four a breadth seating and 47 seats in total. 122 were built between 1957 and 1960 at ASJ and Eksjöverken. In addition seven Y6 and Y8 were rebuilt to Y7. Five were sold to NSB and one to a Danish private railway. It was in service with SJ until 1989.
Y8 was a faster version used in Central Sweden, with the same interior as the X9. They were rebuilt from Y6 and 29 units had their seating reduced from 53 to 36 seats. Some of these have been preserved.
X16 and X17 are electric versions of the Y6 and Y7.
