Siemens Mobility equips Berlin metro with CBTC

On 5 July 2024, Siemens Mobility has won the tender from Berliner Verkehrsbetriebe (BVG) and will introduce a Communications-Based Train Control System (CBTC) on the U5 and U8 metro lines in Berlin for the first time. The Trainguard MT CBTC solution will enable semi-automated operation (GoA2: Grade of Automation) on the U5 line by 2029 and on the U8 line by 2032, increasing capacity on these lines by around 30 %. 

CBTC technology allows headways of less than 100 seconds. This technological advance will also significantly improve the reliability and punctuality of the two metro lines. Siemens Mobility will carry out the conversion during ongoing operations so that trains on both lines of Germany’s largest metro system can continue to run uninterrupted throughout the entire project. The contract has a volume of approximately 200 million EUR, plus additional long-term technology maintenance contracts.

The BVG lines U5 and U8 will be equipped with Trainguard MT over a total route length of 40 km, which includes all 26 stations on the U5 line and 24 stations on the U8 line. When the CBTC is installed, the semi-automated operation will allow trains to communication continuously with the trackside, run automatically at specified safety intervals, perform emergency braking, and accelerate and brake autonomously. The train driver can then concentrate on boarding and alighting passengers, monitor the route visually, and intervene in an emergency. By relying on real-time data on train positions and speeds, more trains can run at shorter headways along the line.  

Digitalization ensures greater efficiency on the rail lines

Siemens Mobility’s Rail Infrastructure Business Unit offers a wide range of intelligent mobility solutions and a diverse product portfolio for various rail markets, including mass transit, mainline, and freight. The company’s Trainguard MT CBTC solution is the leading solution for train control systems. It is currently used by 56 operators on five continents, in 25 countries and 49 cities to optimize their metro and suburban rail systems and operate them more efficiently, sustainably, and economically. Trainguard MT is the most widely used control system worldwide and is currently deployed on 96 metro lines, in 4,351 trains transporting more than 30 million passengers daily.
