The Y1 is a diesel-hydraulic 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.
Y1 is based on the Italian model ALn 668. This diesel railcar was built during the period 1954–1981. 787 vehicles were built in 12 series.
SJ, the Swedish railways, needed new 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.
Today most of them are owned by regional transport authorities, not by SJ. The only regular line that use these railcars in planned traffic today is Kinnekullebanan, some Y1 railcars are though many are stationed at different places in Sweden as reserve trains. Most of the railcars are now replaced by Itino trains and have been sold to other countries such as Uruguay and some former Yugoslavian countries. The summer-only tourist service on Inlandsbanan also uses these railcars.
It is classified as series 7122 on the Croatian Railways. Second-hand examples begun arriving from Sweden in 1996, and now total around 20. This units now replace " Šinobus " units on branch lines. The 7122 is used in Istria, Dalmatia and around Bjelovar.
Almost all of the incoming units were converted to standard orange-black livery. However, in 2007, a new livery consisting of silver, blue and red was being implemented.
It is classified as series 710 on the Serbian Railways. Second-hand examples begun arriving from Sweden in 2005. They are all coloured in white, blue and black livery. The units are being retired as new Class 711 enters service.
Norges Statsbaner operated two units on the Bratsberg Line, between Porsgrunn and Notodden, until August 2015. The units did not follow the nominal naming classification of NSB, and were referred to as Y1. The cars were not painted in NSB's usual red color scheme, but a more orange type of red, and were acquired used from the Swedish railways.
A total of four former SJ Y1 (1281, 1304, 1306, 1313) were sold in 2007 to Kosovo Railways for local trains between Pristina and Peć. The railcars were renumbered 01, 02, 03, 04 (but still carry their old numbers below the new numbers) and have a red and yellow livery.
Five Y1 type railcars were sold to Uruguay. Railcars 1273, 1310, 1317 and 1354 are active in local services around Montevideo (February 2017). 1333 is not in use. In 2016, seven more coaches were acquired, but they are still waiting to be shipped to that country.
