TheY1is adiesel-hydraulicstandard gaugerailcar(single self-propelling carriage). It is in use inCroatia,Serbia,Kosovo,Sweden andUruguay. The production of the railcars was begun in 1980 byKalmar VerkstadandFiat Ferroviariafor Sweden.

Italy

The Y1 is based on the Italian modelALn 668.This diesel railcar was built during the period 1954–1981, with 787 built.

Sweden

SJ,the Swedish railways, needed new diesel railcars for lines likeInlandsbanan.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 inKalmar,Sweden. 100 vehicles were made during the period 1979–1981.

There were some variations, with some having a cargo area, needed in the remote parts of northern Sweden where mail and parcels are often transported by passenger buses and trains. They have 68 or 76 seats, but 48 only in those equipped with a cargo area. As first delivered, the vehicles had Fiat engines. During the 1990s several were updated and acquired newVolvoDH10 bus engines.

Many Y1s have been resold to other countries such as Uruguay and some of the former Yugoslavian countries.

Most of the Y1s in Sweden were in the 2000s owned by regional transport authorities, rather than bySJ AB,where they have been replaced byBombardier Itinotrains. The last regular line to use these railcars in regular traffic wasKinnekullebanan,run byVästtrafik,in 2019. A number of Y1 railcars were nevertheless stationed at different places around Sweden as reserve trains. The winter/summer tourist service onInlandsbananare now the only passenger operator of these railcars, except for several heritage railways. Other companies use Y1 for track maintenance andTrafikverkethas converted one Y1 to a conference car.

These units have replacedHŽ series 7221Šinobusunits on branch lines. The 7122s are used inIstriaandDalmatiaand aroundBjelovar,Varaždin,OsijekandKarlovac.

Almost all of the incoming units were painted in standard orange-black livery. However, since 2007, a new, silver, blue and red livery was introduced. Some units are also coloured in silver livery, with a blue stripe on the bottom and modern HŽPP logo above.
