Bombardier Itino is a diesel multiple unit (DMU) produced by Bombardier Transportation, initially designed by Adtranz. Manufactured from 2002 until 2010 at the former LEW Hennigsdorf facility, a total of 57 trainsets were completed. These units, available in two- or three-car configurations, achieve speeds of and are utilized in both Germany and Sweden.
Germany
In the German rail network, the Itino is classified as DB Class 613 and operates primarily on the Odenwaldbahn and Erfurter Bahn lines, with 27 units currently active.
Sweden
Within Sweden, the Itino is identified as Y31 for two-car sets and Y32 for three-car sets. Thirty of these units are in service with operators including , Kalmar Länstrafik, Norrtåg, Värmlandstrafik, and Västtrafik. This model replaced the older Y1 railcars.
Technology
The trains are equipped with two diesel engines from MAN, which are adaptations of truck engines but with increased cylinder capacity, also utilized in marine and power generator contexts. They feature hydraulic transmissions. Models produced between 2008 and 2010 incorporate Iveco engines that comply with contemporary truck emission standards, combined with mechanical automatic gearboxes supplied by ZF Friedrichshafen. The characteristic angled window pillar design was first introduced by ABB/ADtranz on the Regioshuttle.
Brake problems
In Sweden, the Itino units encountered braking difficulties during snowy conditions, causing winter service interruptions mainly affecting and SJ AB on the Västerdalsbanan, where the initial two units were deployed. Comparable braking issues were reported by other Swedish operators such as Norrtåg during the 2011–12 winter season. Due to persistent reliability concerns, the Swedish Y31 and Y32 fleets are planned to be replaced by new bi-mode CAF Civity Nordic trains manufactured by CAF, scheduled for delivery between 2024 and 2027.
