Rhein-ruhr Systemtechnik

What Rhein-ruhr Systemtechnik does

Rhein-Ruhr Systemtechnik GmbH (RRS) is a German engineering services and system technology provider founded in July 2017, headquartered in Bochum-Langendreer with a second site at the former Westerholt mine in Gelsenkirchen (opened 2022). The company specializes in digital solutions and lifecycle services for critical rail and industrial infrastructure, with a particularly deep focus on legacy and modern German railway signaling and telecommunications systems, including relay-based interlocking platforms (SpDrS60, SpDrS59, DrS2), electronic interlockings (ESTW SIMIS-C), train numbering and tracking systems (ZNP801, ZLV-Bus), and operational telecom systems (DVS-21, VoIP-Com, DIKOS210, MACS, GSM-R terminals via Frequentis DICORA).

Technically, RRS combines hands-on field engineering with embedded software development. Its engineering staff builds Linux-based embedded software in C/C++ for ITK communications infrastructure using VoIP/SIP/RTP protocols, and has integrated Microsoft Teams as a telephony endpoint within telecom systems. A distinctive asset is the company's own training and testing facilities — the Stellwerk Lpf in Bochum housing multiple interlocking generations, plus a SpDrSL60 test facility in the former Westerholt mine control room — which allow real-condition validation of new products and interfaces that competitors reliant on simulators cannot replicate.

Commercially, RRS operates a professional services and system integration model with four interlocking revenue streams: (1) 24/7, 365-day on-site technical service (maintenance, troubleshooting, commissioning, remote maintenance operation); (2) training programs launched in 2024 for maintenance technicians covering SpDrS60 (Parts 1 & 2), DUS 501/502 pulse-code remote control, and the S60 numeric control desk; (3) digital solutions including retrofit/obsolescence management, PLC migration, IoT/Industry 4.0 plant monitoring, and predictive failure analysis; and (4) product sales of replacement hardware and communication systems as an authorized ProCom partner. Pricing is quote-based and individually negotiated with no public disclosure. The go-to-market is enterprise field sales directed primarily at railway infrastructure operators, with secondary reach into industrial and transportation facilities, regionally concentrated in North Rhine-Westphalia. The company is privately held by managing director Markus Wernet with no disclosed outside investors.

Core offering

Rhein-Ruhr Systemtechnik provides on-site technical services, retrofit/obsolescence solutions, simulation and plant monitoring technology, IoT/Industry 4.0 solutions, and technician training programs for railway signaling (interlocking systems) and operational telecommunications systems. The company supports both legacy relay interlockings (SpDrS60, SpDrS59, DrS2) and modern electronic interlockings (ESTW SIMIS-C), and is an authorized partner for ProCom communication systems (DVS-21, VoIP-Com). It also operates its own training and testing facilities housing multiple interlocking system generations for hands-on product development and customer training.

Product overview

Rhein-Ruhr Systemtechnik is a railway infrastructure technology company offering an integrated portfolio of railway signaling and interlocking systems (SpDrS60, SpDrS59, DrS2, ESTW SIMIS-C), operational telecommunications equipment (DVS-21, VoIP-Com, DIKOS210, MACS, GSM-R terminals), and train tracking systems (Zugnummernmeldeanlagen, ZLV-Bus). These core products form the backbone of their service offerings which include 24/7 technical service with remote maintenance capabilities, maintenance training courses for specific systems (SpDrS60 Teil 1/2, DUS 501/502, Nummernstellpult S60), retrofit and obsolescence management solutions, IoT/Industry 4.0 plant monitoring, and telecommunications infrastructure installation. The company operates training and testing facilities at both locations (Bochum-Langendreer with multiple interlocking systems and Westerholt with SpDrL60) to provide hands-on training and test new product ideas and interfaces under real conditions.

Recent moves1 record

Broad incumbents

• Hitachi Rail: Hitachi Rail (including the former Thales GTS business) supplies signaling and digital rail solutions across Europe and overlaps with RRS in rail interlockings and communications services.
• Thales Transport & Security: Major global rail signaling and communications supplier covering interlockings, ETCS and telecom subsystems. Overlaps with RRS on rail comms and signaling lifecycle work, competing on larger modernization and digitalization programs.
• Siemens Mobility: Siemens Mobility is the manufacturer of ESTW SIMIS-C, one of the core systems RRS services and trains on. It is the dominant full-scope rail signaling and interlockings supplier in Germany and competes broadly with RRS in modernization and service contracts, though at vastly larger scale and with a multi-country footprint.
• Alstom Transport: Global rail OEM and signaling provider with a strong German footprint and a broad portfolio that competes for both signaling systems and services contracts targeted by RRS.

Direct peers

• Scheidt & Bachmann: German specialist in rail signaling, interlocking and level-crossing systems with longstanding presence in the German market. Comparable to RRS in serving railway operators with signaling technology and lifecycle services, but operates at significantly larger scale.
• Frequentis: Austrian vendor of rail communication systems including GSM-R terminals (DICORA), explicitly referenced as a partner/product in RRS's portfolio. Directly comparable in the rail operational telecommunications niche, with deeper product breadth and international reach.
• SPITZKE SE: German rail infrastructure services company providing track, overhead line, signaling and interlocking maintenance and construction. Closely comparable to RRS in delivering specialized rail technical services in Germany, though at substantially larger headcount and project scale.
• Balfour Beatty Rail: European rail infrastructure services contractor offering signaling, telecom and maintenance services to operators. Comparable business model in delivering rail technical services, primarily outside Germany but active in adjacent markets.
• HANNING & KAHL: German supplier of rail point machines, interlockings and level-crossing technology with service offerings in Germany. Overlaps with RRS in signaling equipment lifecycle support for German rail infrastructure.
