Munich U-Bahn Network: Expansion and Modernisation Project Profile

The Munich (München) U-Bahn is a critical rapid transit system undergoing significant expansion and technological modernisation to enhance urban mobility and meet future capacity demands. This project profile outlines the ongoing upgrades to rolling stock, signalling infrastructure, and network extensions, including the planned U9 and U29 lines. The initiative represents a multi-billion Euro investment in sustainable public transport, reinforcing the network’s role as the backbone of the city’s infrastructure.

Project Fact Sheet

Technical Specifications

The Munich U-Bahn’s modernisation programme is focused on two primary areas: rolling stock renewal and infrastructure enhancement. The fleet is being systematically upgraded with the introduction of new Class C2 trains manufactured by Siemens Mobility. These six-car articulated trains offer a 10% increase in capacity compared to their predecessors and are equipped for advanced operational modes, including manual operation (FO) and automated train control via the Linienzugbeeinflussung (LZB) system. The long-term strategy aims to replace approximately 60% of the fleet by 2025 to manage asset aging and improve service reliability.

Infrastructure upgrades are concurrent with fleet modernisation. Key interchange stations such as Hauptbahnhof, Marienplatz, and Sendlinger Tor are undergoing extensive renovation to handle increased passenger flow. The network’s power supply is being enhanced to support higher service frequencies, particularly during peak hours. Future-facing developments include the planning of the new U9 relief line to decongest the city centre and the fully automated U29 line, signalling a strategic shift towards Grade of Automation 4 (GoA4) operation. These expansions, along with extensions to existing lines like the U5 to Pasing, are critical for the network’s long-term sustainability and efficiency.

Key Takeaways

• Systematic Fleet Modernisation: Munich is executing a long-term strategy to replace its aging rolling stock with high-capacity, technologically advanced C2 trains, enhancing both passenger experience and operational efficiency.
• Strategic Network Expansion: The planned U9 and U29 lines are a direct response to urban growth, designed to increase network capacity, provide critical redundancy, and alleviate congestion on core city-centre routes.
• Commitment to Technological Advancement: The adoption of automated train control (LZB) and the future implementation of fully automated (GoA4) lines demonstrate a clear commitment to leveraging technology for safer and more reliable public transport.

Frequently Asked Questions (FAQ)

When will the new Munich U9 line open?

The U9 line is a major planned expansion currently in the detailed planning and approval phase. While an official opening date has not been finalized, current projections estimate completion and commissioning in the 2030s, pending the completion of all regulatory and construction stages.

Who is building the new Munich U-Bahn trains?

The new generation of high-capacity trains, designated as Class C2, are being designed and manufactured by Siemens Mobility. This procurement is part of a substantial, long-term contract with Stadtwerke München (SWM) to modernise the U-Bahn’s rolling stock fleet.
