Bombardier Itino is a diesel multiple unit produced by Bombardier Transportation, initially designed by Adtranz. Manufactured from 2002 to 2010 at the former LEW Hennigsdorf facility, a total of 57 units were assembled in configurations of two or three cars, with maximum speeds reaching . These trainsets are currently in operation within Germany and Sweden.
Germany
In Germany, these trains are classified as DB Class 613 and number 27 units, serving routes on the Odenwaldbahn and Erfurter Bahn networks.
Sweden
Within Sweden, the units are identified as Y31 for two-car sets and Y32 for three-car formations. Thirty units run services under , Kalmar Länstrafik, Norrtåg, Värmlandstrafik, and Västtrafik, replacing the former Y1 railcars.
Technology
The Itino is equipped with dual MAN diesel engines, adapted from truck engines but featuring enlarged cylinders ( each), also utilized in marine and generator contexts. The propulsion system employs hydraulic transmission. Models produced between 2008 and 2010 incorporate Iveco engines compliant with current truck emission regulations, coupled with ZF Friedrichshafen mechanical automatic gearboxes originally designed for heavy vehicles.
The train’s characteristic slanted window pillar design was initially introduced by ABB/ADtranz on the Regioshuttle model.
Brake problems
In Sweden, the multiple unit encountered initial difficulties during winter due to braking systems that were insufficient for snowy conditions. This led to service interruptions mainly affecting and SJ AB on the Västerdalsbanan line, where passenger operations ceased in 2011. Other Swedish operators, including Norrtåg, reported similar issues during the winter of 2011–12. In addition to braking complications, these trains have experienced various quality-related problems. As a result, the Swedish Y31 and Y32 fleets are planned to be replaced by new bi-mode CAF Civity Nordic trains between 2024 and 2027.
