Chemnitz’s New Tram-Trains: Stadler Citylink Arrives

This article examines the significant contract awarded to Stadler by the Verkehrsverbund Mittelsachsen (VMS) (Mid Saxony Transport Authority) for the delivery of modern tram-trains to the Chemnitz network in Germany. This procurement represents a substantial investment in upgrading the region’s public transportation infrastructure, showcasing the growing importance of efficient and integrated rail systems within urban and interurban contexts. The project encompasses not only the manufacturing and delivery of the new vehicles themselves, but also the construction of a state-of-the-art depot and significant financial commitments from various sources, underscoring the complexity and collaborative nature of large-scale public works projects. The analysis will explore the technical specifications of these innovative tram-trains, the economic aspects of the project financing, and the broader implications for the future of public transport in Chemnitz and the surrounding region. This case study serves as a prime example of how investment in modern rolling stock and infrastructure can transform regional mobility, enhancing accessibility and potentially stimulating economic development.

Stadler’s Citylink Tram-Trains: Technical Specifications and Innovations

Stadler, a prominent Swiss railway rolling stock manufacturer, has secured a contract to supply 19 dual-system Citylink tram-trains, with an option for 27 more, to VMS. These three-section vehicles represent a second generation of tram-trains, incorporating several key advancements. Measuring 37.5 meters in length, each tram-train boasts a capacity of 236 passengers, including 88 seated. Accessibility is a key feature, with four double doors on each side and designated areas for prams, wheelchairs, and bicycles. Passenger information is enhanced by a dynamic passenger information system and a radio-controlled system for visually impaired passengers. The robust drive system, with 900 kW of power, enables a top speed of 100 km/h, facilitating efficient operation on both the city’s 600/750V DC network and the 15 kV 16.7 Hz mainline network, thereby seamlessly integrating urban and regional rail services. This dual-system capability is crucial for optimizing operational flexibility and passenger convenience.

The Chemnitz Network Expansion: Routes and Infrastructure Development

The new Citylink tram-trains will significantly enhance the Chemnitz network, serving existing lines to Mittweida, Glauchau (via Stollberg and Oelsnitz), Burgstädt, and Hainichen. Furthermore, they will operate on the planned 17-kilometer Step 4 line connecting Chemnitz city center to Limbach-Oberfrohna. This expansion demonstrates a commitment to extending reliable and efficient public transport beyond the city limits, contributing to improved regional connectivity and accessibility. The project’s scope also includes the construction of a new depot at Sachsen-Allee in Chemnitz, scheduled for completion in 2026. This substantial investment in infrastructure underlines the long-term vision for upgrading the region’s public transport system and ensuring the smooth operation and maintenance of the new tram-trains. The depot will play a crucial role in the efficient management of the fleet and overall service reliability.

Project Financing and Economic Impact

The overall project cost is estimated at €234.56 million, encompassing the procurement of the tram-trains, construction of the new depot, and ongoing maintenance. Funding will be secured through a combination of loans and subsidies from the state of Saxony, alongside contributions from the Zentraler Verkehrsverbund Mitteldeutschland (ZVMS) (Central Saxony Special Purpose Transport Association). This collaborative financing model demonstrates a commitment from various stakeholders to invest in improved public transport infrastructure. The economic impact extends beyond direct job creation during construction and manufacturing; the improved public transport system will enhance regional accessibility, potentially stimulating economic growth by making commuting easier and encouraging investment in the area.

Project Timeline and Service Commencement

Stadler is scheduled to begin delivering the tram-trains in the summer of 2025, with passenger service expected to commence in June 2026. This timeline highlights the significant planning and logistical challenges associated with large-scale infrastructure projects. The coordination between Stadler, VMS, and other stakeholders will be crucial for adhering to this schedule and ensuring a smooth transition to the new service. The successful implementation of the project will significantly enhance the efficiency and effectiveness of public transport in Chemnitz and the surrounding region, setting a precedent for future investment in similar projects across Germany and beyond.

Conclusions

The Stadler contract for the supply of 19 Citylink tram-trains to the Chemnitz network represents a significant milestone in the modernization of Germany’s regional rail infrastructure. The project showcases the increasing importance of integrated urban and interurban transport solutions, highlighting the benefits of dual-system vehicles capable of seamless operation on both city and mainline networks. The investment of €234.56 million, sourced from a collaboration between the state of Saxony and the ZVMS, demonstrates a significant commitment to improving public transport accessibility and stimulating regional economic growth. The state-of-the-art features of the tram-trains, including increased passenger capacity, accessibility provisions, and advanced passenger information systems, promise to significantly enhance the passenger experience. The construction of a new depot underscores the commitment to long-term operational efficiency and maintenance. The project timeline, with delivery commencing in summer 2025 and passenger service starting in June 2026, reflects careful planning and a dedication to timely implementation. The success of this project will undoubtedly serve as a compelling case study for future rail modernization initiatives across Europe, illustrating the economic and social benefits of investing in efficient, integrated public transportation systems. The detailed specifications of the tram-trains, their advanced technology, and the comprehensive infrastructure development highlight a forward-thinking approach to modernizing public transport in Chemnitz, emphasizing sustainability, accessibility, and improved connectivity. The collaborative funding model showcases a successful strategy for large-scale public works projects, demonstrating the potential for strong public-private partnerships to drive positive change in urban mobility.
