Digital depot – and its added value
The fully digitalized depot enables efficient maintenance, reduces unplanned downtime and needless depot stops, as well as superfluous component replacement. Thanks to continuous monitoring during operation, the trains provide valuable data for predictive maintenance.
In this way, we opt for state-of-the-art technologies and a pit stop principle for the vehicles in order to optimize planning and maintenance – for up to 100% fleet availability in service.
AI-powered pit stops for trains
The Rhein-Ruhr-Express (RRX) fleet operates around the clock. One reason for this is that artificial intelligence helps monitor the status of train components, with many processes running automatically.
Advantages of the digital depot
reduction of avoidable depot stops
fleet availability thanks to predictive maintenance
Efficient maintenance with Railigent X
Thanks to comprehensively networked processes using Railigent X, the digital depot ensures fast, resource-efficient, and optimally coordinated workflows. The data-based operating principle maximizes system availability and can reduce maintenance costs . Operators benefit from accurate condition data, optimized fleet planning, and increased utilization – for maximum fleet availability in service.
Our infrastructure in the Rail Service Center Dortmund
In addition to digitalized processes, at the Rail Service Center Dortmund (RSC-D) we have a comprehensive maintenance infrastructure featuring state-of-the-art technologies: an exterior cleaning facility, an underfloor lathe, and highly flexible maintenance tracks with track bridges, swiveling overhead contact line, extendable roof work platforms, and much more set us apart. The RSC-D thus makes an important contribution to a sustainable and future-proof railway industry.

Innovative 3D printing at the Rail Service Center Dortmund
We develop and design components using additive manufacturing (3D printing) – tailored precisely to individual requirements. In doing so, we replace discontinued components, redesign the smallest replaceable units, and further develop existing components. The advantages: faster availability, cost efficiency, and functional optimization of component design.
We are growing – our service Depot 2026
Due to the high demand for rail vehicle services, Siemens Mobility is investing around 150 million euros in the expansion of its site in Dortmund. An additional workshop building is planned for the maintenance of rail vehicles with a length of up to 400 m – including storage areas, offices, and workshops. With completion scheduled for 2026, the depot will grow from its current 70,000 m² to a total of 157,550 m². In addition, up to 100 new jobs will be created.
