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. 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 426 is shorter than the class 425

It is also produced in HO scale by a few model railway manufacturers.

Description

[edit]

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 including two of the three jacobs bogies.

It is based on the Class 423 design, but lacks a third set of doorways in the centre of each car.
