Y1 (railcar)

The Y1 is a diesel-hydraulic locomotive standard gauge railcar (single self-propelling carriage). It is in use in Croatia, Norway, Serbia, Kosovo, Sweden and Uruguay. The production of the railcars was begun in 1980 by Kalmar Verkstad and Fiat Ferroviaria for Sweden.

Italy

Y1 is based on the Italian model ALn 668. This diesel railcar was built dring the period 1954–1981. 787 vehicles were built in 12 series.

Sweden

SJ, the Swedish railways, needed new short diesel railcars for lines like Inlandsbanan. SJ bought this model from Fiat. They were based on an existing model, but modified for Swedish needs. The first were produced in Italy, and later in Kalmar, Sweden. 100 vehicles were made during the period 1979–1981.

There were some variations, some had a cargo area, needed in the remote parts of northern Sweden where mail and packages are often transported by the passenger buses and trains. They have 68 or 76 seats, but 48 for those with cargo area. In the beginning the vehicles had Fiat engines. During the 1990s several were updated and got new Volvo DH10 bus engines.
