TheClass 425 andClass 426 EMUs are a class ofelectric multiple units built by a consortium of Siemens, Bombardier and DWA, and are operated byDB Regio in Germany. They are essentially the same vehicle design, but the Class 425 EMU consists of four carriages, whereas the Class 426 EMUs only have two carriages.
The class 425 has been produced inHO scale by Brawa andN scale byKato Precision Railroad Models.
It is a high-powered,light-weight vehicle with high acceleration for short- and medium-distance services with frequent stops. Thealuminium superstructure was built as flat as possible, both to minimize drag and to ease automated cleaning. The acceleration is achieved by distributingtraction motors among eight of the train's ten axles.
The Class 425 are similar toDeutsche Bahn'sClass 424 andClass 423 trainsets.
A Class 425 unit consists of four cars that share threejacobs bogies and can only be separated at maintenance facilities. The inner two cars are designated asClass 435. A 425 unit typically consists of the following cars, wherex is the unit's number:
e.g. 425 153 + 435 153 + 435 653 + 425 653. Different consists usually occur when the remains of partially destroyed units are combined to form one intact EMU.
