Bombardier Itino


The Bombardier Itino is a family of diesel [multiple unit|diesel multiple units] manufactured by Bombardier Transportation, originally developed by Adtranz. Trains of the family have two or three cars and are capable of speeds of around. First introduced in 1998, a total of 57 units were manufactured at the former LEW Hennigsdorf factory between 2002 and 2010. The trains are in service in Germany and Sweden.

Railways

Germany

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

Sweden

In Sweden, the unit has the designations Y31, designating 2-car trains, and Y32, designating three-car trains. 30 units have been delivered and are currently operated by, Kalmar Länstrafik, Norrtåg, Värmlandstrafik and Västtrafik. The Itino replaced the Y1 railcars.

Technology

The trains have two MAN diesel engines. The engines are based on truck engines, but larger, also used for boats and electrical generators. They have hydraulic transmission. Units built between 2008 and 2010 feature two engines from Iveco 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.

Brake problems

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 with its traffic on Västerdalsbanan 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. 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.
