DBAG Class 423
The Deutsche Bahn Class 423 EMU is a light-weight articulated electric railcar for S-Bahn commuter networks in Germany. The train has similar dimensions to its predecessor, the Class 420 EMU, but is significantly lighter and has one large passenger compartment, while that of the 420 is divided into three parts. The 423 additionally has six doors in each carriage (three on each side), which is down from eight on the 420 (four on each side). They are numbered from 423 001 to 423 462.
Both Munich and Frankfurt ordered Class 423s for their S-Bahn systems; they were delivered between 1999 and 2004. The 423 has spawned a family of slightly modified designs ordered for S-Bahns across Germany: the Class 422, Class 424, Class 425/426 and Class 430.
A Class 423 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 433. A 423 unit typically consists of the following cars, where x is the unit's number:
e.g. 423 194 + 433 194 + 433 694 + 423 694. Different consists usually occur when the remains of partially destroyed units are combined to form one intact EMU.
Two short trains form a "full train", three short trains form a "long train".
One can see through from one end to the other of the vehicle, and in the original design a lockable door was installed in the middle of the railcar to allow part of the vehicle to be left empty during periods of low demand in order to maintain greater social control through denser occupancy. The railcars have a passenger information system inside, which alternately displays the destination stop and the next stop and is supplemented by a one-time acoustic announcement of the next stop. Furthermore, an announcement is made on which side it will be possible to get off. They are also equipped with a technical check-in system, whereby the driver does not have to monitor the doors himself; this is done by light barriers. In 2007, however, this procedure was temporarily taken out of service until light grids were retrofitted over almost the entire height of the boarding area.
The three-light headlight can be switched from low beam to high beam during operation. Some railcars (423 238 and 423 268 of the Munich S-Bahn) were in operation with LED headlights instead of normal beam headlights, in which the light from green and red LEDs was mixed to achieve a more balanced spectral distribution. With the modernization, all vehicles were converted to warm white LED modules.
The openings of the twelve doors per side[2] are 1300 mm wide.
