The unveiling of Stadler’s new JK metro series marks a significant step in the development of Berlin’s rail network. Compared to the trains that are over three decades old, the new train represents a leap into a new technological era.
While there are hardly any noteworthy differences on the outside, the JK series impresses with a wealth of innovations on the inside. An improved sense of space, more generous space for standing passengers, and vertical grab bars that make gripping ceiling bars unnecessary are just some of the highlights. The angled grab bars also make it easier for wheelchair users to pass through the aisles. In addition, space-saving screens and an integrated size indication on the signs indicating spaces for the severely disabled are part of the modernized interior.
The first test cars have been rolling through the Berlin subway network since January, before being used for the first time in regular passenger service from late summer 2024. The introduction of this new subway train series represents a significant advance in railway technology and lays the foundation for further innovations in the future.
Technological advancement is driven by the collaboration between REO TPM and its customer, ABB. Together, a special DC line Drossel was developed at the end of 2021 for integration into the new subway cars. As an essential component of the powertrain, this Drossel provides important protection against circuit-related current peaks and reduces harmful mains feedback.
A special feature of the DC line Drossel is its EMC compliance, which is ensured by surrounding the Drossel with thick iron sheets. This ensures that electromagnetic interference is reduced to a minimum, which in turn increases the safety and reliability of the subway operation.
