In 2024, ZF is commemorating a century in the railway technology sector. This milestone traces back to 1924 when the company first adapted the Soden transmission for railcars. Over the years, ZF has grown to become a significant supplier in the rail vehicle market, continually advancing its technology and expanding its global reach.
From Soden transmission to modern innovations
ZF’s journey in railway technology began with the TS18.5 Soden transmission, initially designed for passenger cars. Markus Groß, product line manager for railway technology at ZF, noted the strategic benefit of this innovation: “Rail technology alone wasn’t enough for developing new transmission technologies. We leveraged our driveline technology from other applications, particularly commercial vehicles.”
This approach led to the development of products like the Ecomat Rail and AS Rail transmissions, tailored specifically for rail vehicles. ZF has also provided mechanical drive components for a variety of electrified trains, including metros, trams, high-speed trains, and locomotives.
Strategic acquisitions and market expansion
ZF’s role in the rail sector has been reinforced by several strategic acquisitions. In 1995, the company acquired Hurth Bahntechnik GmbH, a rail transmission specialist, and expanded its production and service capabilities. The portfolio grew further with the acquisition of Mannesmann Sachs AG in 2001, which added rail dampers to ZF’s offerings.
Global impact
ZF’s technology is now utilised in rail vehicles worldwide. High-speed trains in China and rapid transit systems in cities from Istanbul to Shanghai depend on ZF components. The company’s yaw dampers are essential for the stability of high-speed trains, including those running through the Channel Tunnel.
Prof. Dr. Peter Laier, Member of the Board of Management of ZF, commented on the company’s long-term commitment: “Sustainable mobility requires reliable rail vehicles, and our 100-year involvement in rail technology underscores our role as a key supplier.”
Integration of digital services
ZF has also embraced digital advancements with services like the connect@rail condition monitoring system. This system improves the predictability of maintenance operations and helps avoid failures and downtimes. It also facilitates better planning for rail infrastructure repairs.
Anniversary exhibition at ZF forum
To celebrate the centenary, ZF will host an exhibition at the ZF Forum in Friedrichshafen, starting in June 2024. This exhibition will highlight significant contributions from ZF and its subsidiaries over the past century. The celebration will also be featured at the InnoTrans trade fair in September.
ZF’s 100-year milestone in railway technology highlights its sustained impact on the industry. From its early adaptation of automotive technology for railcars to its current role as a global supplier of rail solutions, ZF continues to influence the future of railway technology with both historical expertise and modern innovations.
