The Class 425 and Class 426 EMUs are a class of electric multiple units built by a consortium of Siemens, Bombardier and DWA, and are operated by DB Regio in Germany.[1] 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 in HO scale by Brawa and N scale by Kato Precision Railroad Models.
It is a high-powered, light-weight vehicle with high acceleration for short- and medium-distance services with frequent stops. The aluminium superstructure was built as flat as possible, both to minimize drag and to ease automated cleaning. The acceleration is achieved by distributing traction motors among eight of the train's ten axles.
The Class 425 are similar to Deutsche Bahn's Class 424 and Class 423 trainsets.
A Class 425 unit consists of four cars that share three jacobs bogies and can only be separated at maintenance facilities. The inner two cars are designated as Class 435. A 425 unit typically consists of the following cars, where x 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.
