SJ Class Y3

The SJ Class Y3 was a series of diesel-powered railcars operated by Statens Järnvägar (SJ) of Sweden.
== History ==
In all, A total of six units were ever constructed by Linke-Hofmann of Germany in 1966–1967, with electrical equipment supplied by ASEA and they were all delivered Statens Järnvägar (SJ) of Sweden that after they were constructed.
They remained in service until 1990, serving first on the unelectrified services Stockholm – Mora and Malmö – Karlskrona, later on Ystadbanan.
The Y3 served the same purpose as the electric X9-series. A variation of configurations was used, with the production consisting of six motor cars, two cab cars and eleven trailers with motor cars on each end so that the Y3 could have six trailers between.
Although considered to be the first double-decker train used in Sweden, only the first and last cars of a Y3 train were built to a design somewhat resembling a dome car, whereas the middle coaches were all single-decker (unlike in the X40 and Stadler DOSTO).
The series was prone to catching on fire because of the cooling system not working sufficiently for the extremely powerful Deutz diesel engines introduced in place of the slower and less powerful Rolls-Royce engines. This problem was solved through rebuilding the cooling system in the 1970s. Some of the bilevel rail cars were taken out of service in 1982 when the Y3 series was relegated to local traffic on the Malmö – Ystad – Tomelilla route, with the last Y3 coaches being retired in 1990, and none of them were preserved, they were all scrapped.
