Overview of rolling stock components news around the world.
The company has unveiled a bogie supporting motion at 400 km/h. This essential part of the train, which has been successfully tested at 600 km/h, is 20% lighter than existing options for high-speed trains, as its producer reports. The bogie is designed to reduce operational energy consumption by 15%, maintenance costs over the bogie’s life cycle by 15%, and wheel and rail wear by about 30%. CRRC is now developing the CR450 EMU with the highest design speed in the world, 400 km/h.

Key Systems and Components Group (KSC Group) has initiated serial production of traction batteries for the Moscow 2020 and Moscow 2024 metro trains at one of its facilities. These batteries have been designed for use in emergency operations or manoeuvring in a depot when external energy sources are unavailable. By the end of the year, the TMH plant in Mytishchi is expecting 320 batteries.
DAC from Voith. Source: Voith
Europe has selected Voith’s module of the digital automatic coupler (DAC) as the standard for deploying this solution in the region. The decision was made following four months of testing on a demonstrator train and test benches. The module ensures automatic connection of power supply rails and data transmission. The module from Knorr-Bremse was found to be less cost-effective over the product life cycle than Voith’s one. It is anticipated that the adoption of DAC at over 500,000 freight cars operated in the EU will commence in 2028. The project is facing significant criticism from operators in various EU countries, who have highlighted the high costs and lack of clarity surrounding the transition process.
