Siemens Mobility and Ruhrbahn GmbH will digitalize control and safety technology dating from the 1970s in Essen and Mülheim an der Ruhr by 2031 to ensure the system is fit for the future. The contract was signed recently by the partners and includes digitalizing Europe’s largest light rail interlocking system at Essen Central Station. The modernization will make the interlocking system more reliable and energy efficient.
Modernization of the five interlockings with Europe’s currently largest relay interlocking for trams and metros at Essen Central Station will be carried out in five project phases by 2031. During the project, passenger services will be restricted only for short periods in individual sections of the system. The relay technology will be completely replaced, and the system’s control and safety technology will be converted to digital controls, making the infrastructure significantly more efficient. The interlocking at Central Station alone currently sets points around 5,000 times a day and switches signals to green 23,000 times. The electronic interlocking solution Trackguard from Siemens Mobility is currently installed at five interlocking locations.

One special feature of this major project will be the integration of the metropolitan region’s three and four rail systems. The challenge here is to use the different track gauges in the system and enable seamless operations using state-of-the-art technologies.
As part of the project, Siemens Mobility will renew the approximately 28-kilometer-long train control section with 39 stations. The signalling system will be equipped with LEDs, the track vacancy detection system will be upgraded with an axle-counting system, and all magnetic barriers that prevent trains from passing a stop signal will be replaced.
