Munich U-Bahn Upgrades Fleet with New Hybrid Work Vehicles
Munich, May 8, 2026 – The Munich public utilities (SWM) and the Munich transport company (MVG) are significantly enhancing their U-Bahn network’s operational capabilities with the introduction of new, advanced track maintenance vehicles. By December 2026, a total of ten new Robel Rorunner Level 3 E³ work vehicles and eight specialized trailers will join the fleet, aiming to improve efficiency, reduce emissions, and enhance working conditions for personnel. The first units are already undergoing preparatory training runs and will soon be fully operational.
Increased Flexibility and Performance with Ten New Vehicles and Eight Trailers
The new fleet comprises ten four-axle track maintenance vehicles and eight trailers. These vehicles are symmetrically designed for bi-directional operation, a crucial feature given the absence of turning facilities in the Munich U-Bahn network. Each track maintenance vehicle is equipped with two powerful cranes, featuring an eleven-meter-long boom on each side, providing exceptional flexibility for various tasks. Both cranes can be operated independently, allowing for simultaneous and diverse operations.
These vehicles will primarily be used for track construction work and logistical transport within the U-Bahn system. Among the eight trailers, two four-axle units are designated for logistical operations, while six two-axle trailers are intended for track construction work. The range of materials transported by these new vehicles is extensive, including escalators, rail sections, switch components, tools, construction debris, and various building materials, highlighting their versatility and importance for the U-Bahn’s maintenance and expansion.
Hybrid Drive for Enhanced Performance and Reduced Emissions
A significant innovation in these new vehicles is their hybrid drive system. For the first time, not only the cranes but also the drive motor are electrically powered. This power is supplied via the U-Bahn’s current rail and supplemented by high-performance batteries. These batteries can be charged during operation from the current rail and also recover energy through recuperation, significantly reducing noise and exhaust emissions. This advancement particularly benefits the workers, as it creates a quieter and healthier working environment. Further improving working conditions is the spacious and air-conditioned cabin, designed for operator comfort.
The new vehicles also demonstrate improved climbing capabilities, especially when starting on inclines, which accelerates work processes. For extended operations outside the current rail’s range or when the power supply is switched off for safety reasons, the vehicles are equipped with a diesel engine. This ensures continuous operation by providing the necessary energy once the battery capacity is depleted, offering a reliable backup for critical tasks.
Commitment to Modernization and Sustainability
The investment in these state-of-the-art work vehicles underscores SWM and MVG’s commitment to modernizing Munich’s public transport infrastructure. By integrating advanced technology and hybrid propulsion systems, the city aims to ensure a more sustainable and efficient U-Bahn operation. This initiative not only supports environmentally friendly practices but also enhances the safety and well-being of the workforce, contributing to a more reliable and effective public transport system for Munich’s residents.
The deployment of these new vehicles is expected to streamline maintenance schedules, reduce operational costs in the long run, and minimize disruption to passenger services. As the first units begin their service, Munich’s U-Bahn network is set to experience a significant uplift in its operational capabilities, paving the way for a more advanced and sustainable future.
