MUNICH – Knorr-Bremse has been awarded a major long-term remote condition maintenance contract with Siemens Mobility. As Knorr-Bremse systematically develops its expertise in digital maintenance as a service (MaaS) for the rail industry, the company will be responsible for providing remote monitoring of the condition of HVAC systems on 172 trains built. and maintained by Siemens Mobility for the British operator South Western Railway.
The upgrade and modernization of the HVAC systems began in 2021 and is expected to be completed in the first quarter of 2022, so that the new solution can be put into service in the spring of the same year.

Dr. Jürgen Wilder, Member of the Executive Board of Knorr-Bremse AG and Head of the Rail Vehicle Systems Division, explained the importance of the order: “The rail industry has enormous untapped digitization potential due to factors such as high safety standards, investment requirements and the need to become even more efficient. Against this backdrop, we continue to consistently build Knorr-Bremse as a digital systems provider and expand our portfolio of remote condition maintenance solutions. Therefore, we are delighted to have established this digital partnership with Siemens Mobility. This contract is a first for the rail industry and will help the operator to offer its passengers an even more sustainable, affordable and modern rail service.
Dr. Nicolas Lange, Chairman of the Board of Knorr-Bremse Rail Vehicle Systems, elaborated on these comments: “We are delighted to have signed this important contract, which further strengthens our partnership with Siemens Mobility in the area of digital services. By upgrading several large passenger train fleets with our remote condition maintenance solutions, we are helping bring them into the digital age. Big data information and new CO2 sensors will optimize fleet maintenance costs, reduce train energy consumption and even more precisely control the flow of fresh air in passenger compartments.
Operational optimizations and energy savings through intelligent data analysis
In 2021, Knorr-Bremse began upgrading a total of 733 HVAC systems on 172 trains with its digital remote condition monitoring solution, improving the condition maintenance capability (CBM) of Siemens Mobility. The fleets consist of 45 five-car class 444 regional trains and 127 four-car class 450 regional trains. The original HVAC systems were manufactured by Merak, Knorr-Bremse’s global subsidiary for air conditioning solutions for trains. The upgrade will allow them to capture large amounts of operating data which will then be intelligently analyzed by Knorr-Bremse via the cloud.
