Siemens Mobility has commissioned Knorr-Bremse to equip the latest generation of Munich S-Bahn trains with braking systems and, for the first time, with coupling systems. The schedule for delivery of up to 90 lightweight trains starts at the end of 2028. They will also be deployed on Munich’s second main S-Bahn line, which is currently under construction.
By supplying braking systems and center buffer couplers for the S-Bahn trains, Knorr-Bremse will contribute to fulfilling the customer’s expectations on optimised lifecycle costs, improved energy efficiency and highest possible vehicle availability. The braking systems include magnetic track brakes (MTBs), pneumatic brake control systems, bogie equipment and the latest generation of ScrewSupply Eco screw-type compressors. The new compressor optimises maintenance and overhaul cycles, and further reduces noise emissions by using smart components such as electrically controlled fans.
Knorr-Bremse is scheduled to start series delivery of the automatic couplers at the end of 2025.
Siemens Mobility opted for coupling technology on the basis of its modularity, exceptional reliability and optimised lifecycle costs. Since successfully entering the international market for coupling systems, Knorr-Bremse has developed a range of modular couplers for various types of trains and has been awarded several major orders.
The Siemens Mobility order also includes wiper/wash systems for the new trains. The two companies already have a long history of collaboration in this product segment, and this project adds yet another chapter. Knorr-Bremse’s wiper/wash systems are already used on Siemens Mobility’s Mireo train platform.
In August 2023, Siemens Mobility won a EUR 2 billion contract to supply Munich 90 S-Bahn trains including an option for more trainsets. An agreement was signed for the financing of this contract with the European Investment Bank (EIB) and the German affiliate of UniCredit, HypoVereinsbank. In October 2024 Wabtec announced that it will supply and install passenger information systems for the entire train fleet.
The 13-car Munich S-Bahn trains will be 202-metre long with a capacity of up to 1,841 passengers. The trains will supplement the existing fleet, enhancing the capacity of Munich’s urban and regional transit systems.
