Relay interlockings in Essen and Mülheim an der Ruhr, Germany, will be replaced by electronic interlockings
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, worth around €180 million, was signed recently by the partners and includes digitalizing Europe’s largest light rail interlocking system at Essen Central Station. Sixty percent of the costs for the renewal of the interlockings will be funded by the municipal rail renewal program with state and federal funds; the funding is currently expected to total around €96 million. 
 
“After decades of wear and tear and the interim refurbishment of the relay technology in three of our five interlockings, we are now undertaking the complete renewal and digitalization of the train control and safety technology for tram and light rail transport in Essen and Mülheim an der Ruhr. Our aim is to make the existing network more efficient and reliable. When the renewal project is completed, there will be fewer disruptions and downtimes, making the use of public transport even more attractive for our passengers,” explains Michael Feller, CEO of Ruhrbahn. 
 
Guido Rumpel, Head of Rail Infrastructure Germany at Siemens Mobility says: “Reaching the goal of climate-neutral mobility will require a significant increase of passenger capacity in public rail transport. Smart cities are tackling and solving this challenge with modern technology. We are delighted that Ruhrbahn is converting its rail system to be fit for the future and that we have been chosen to implement this project with state-of-the-art control and safety technology by 2031. The digitalization of Europe’s largest light rail interlocking in Essen marks a great technological leap forward for rail operations. Once completed, passengers will benefit from a more reliable and punctual rail system.” 
 
As part of the project, Siemens Mobility will renew the approximately 28-kilometer-long train control section with 39 stations. The signaling 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
