European Driver's Desk
The European Driver's Desk (EUDD) is a new, manufacturer-independent European standard for the driver's desk in railway vehicles. The arrangement of the display instruments in the EUDD is based on the DB standard driver's cab , but differs in terms of the operating philosophy. In particular, because of the computer control of the traction and braking forces that are generally used today, the division of the main operating elements into a traction lever, a lever for the pneumatic brake and one for the dynamic brake is no longer felt to be up-to-date. The EUDD combines traction control and dynamic brakes in a drive / brake lever with a central position. A driver's brake valve (FbV) with time-dependent control is generally available for the indirect brake . FbV of this type are no longer common in Germany (position-dependent FbV have been used here since the post-war period), but are widespread in the rest of Europe. The specification of the EUDD extends not only to the operating elements but also to the screen presentations of the displays in the driver's cab.
The development phase of the EUDD driver's cab ran from 2001 to 2003. Specific implementations were then implemented by various locomotive manufacturers, such as Bombardier in the TRAXX 2E .
The latest status of standardization since 2010 has been the so-called EUDDplus. This differs in details from the EUDD. A keyboard for textual data entry is specified centrally in front of the operator. The V soll controller of the automatic speed control, implemented as an up-down controller in the EUDD, is again designed as a wide-range controller in the EUDDplus, as in the DB standard driver's cab. The Alstom Prima II was the pilot platform for the EUDDplus .
In practice, some manufacturers' EUDD traction vehicles showed inadequacies in the vehicle software, which meant that pushing movements were only possible with auxiliary measures. In the affected series, the brake and traction power are interlocked by the software so that it is not possible to switch on power when the brake is applied, but this is often necessary for (dis) coupling in order to compress the buffers.
