Bombardier Itino is a diesel multiple unit manufactured by Bombardier Transportation, originally developed by Adtranz. It has two or three cars and is capable of 140–160 km/h (90–100 mph). A total of 57 units were manufactured at the former LEW Hennigsdorf factory between 2002 and 2010. It is in service in Germany and Sweden.

In Germany it has been designated as DB Class 613 and is operated on Odenwaldbahn and Erfurter Bahn. Twenty-seven units are currently operated by the two railways.

In Sweden the unit has the designation Y31 and Y32, the latter for the three-car formation. 30 units have been delivered and are currently operated by Jönköpings Länstrafik [sv], Kalmar Länstrafik, Norrtåg, Värmlandstrafik and Västtrafik. The Itino replaced the Y1 railcars.

The trains have two MAN diesel engines. The engines are based on truck engines, but larger (each 22 L (1,343 cu in)/cylinder volume), also used for boats and electrical generators. They have hydraulic transmission. Units built between 2008 and 2010 feature two engines from Iveco (also based on truck engines) and they fulfill the latest environmental requirements for trucks. They also have mechanical automatic gearboxes from ZF Friedrichshafen meant for trucks.

The distinctive angled window pillar bodyshell construction was previously introduced by ABB/ADtranz on the Regioshuttle.

The multiple unit got a bad start in Sweden, when it was shown that the brakes could not cope with snow. This has led to the model being suspended during the winter for oversight, which mostly affected Tåg i Bergslagen [sv] (and SJ AB which at the time was taking them into service) with its traffic on Västerdalsbanan (passenger traffic ceased in 2011) where the two first units were used. It has also from time to time affected other operators in Sweden, such as Norrtåg in the winter of 2011–12.^[1] There has been a lot of other quality problems with these trains. For this reason, the Swedish Y31 and Y32 trains will likely be replaced by new CAF Civity Nordic bi-mode trains between 2024 and 2027.^[2][3]
