Railway rolling stock

Safe, comfortable and more efficient rail transport

Liebherr is a key player in the rolling stock market, offering innovative solutions across all segments, from light rail vehicles to high-speed trains. Rolling stock manufacturers worldwide rely on advanced Liebherr technologies and services.

HVAC Systems

Liebherr provides heating, ventilation, and air conditioning (HVAC) systems for railway rolling stock, focusing on low-GWP (global warming potential) refrigerants like CO2 and propane. Liebherr excels in air cycle technology that uses no refrigerants. Further, Liebherr has developed a modular air-conditioning system, which serves as a universal HVAC standard for multiple railway platforms

Hydraulic systems

Both passive and active hydraulic systems are available for various railway applications, including braking, damping, axle steering, and levelling. These systems enhance safety, stability, and comfort by delivering precise control and responsiveness for railway vehicles. Looking to improve the longevity of the rail infrastructure, Liebherr’s active controlled axle steering system considerably reduces wear on tracks and wheels.

Meeting regional standards

Liebherr maintains a network of local offices and experts, ensuring the products meet regional standards and regulations. By adapting products through collaborative partnerships and an understanding of operational characteristics, Liebherr provides tailored, compliant, and effective solutions. Continuous innovation and localized expertise allow Liebherr to address the specific needs of different regions effectively.

Solutions for railway

"Brake-by-wire"

Siemens and Liebherr develop electro-hydraulic brake actuator

Following the trend of air-free technology on board rolling stock, Liebherr, in collaboration with Siemens, developed an electro-hydraulic brake actuator. Unlike the conventional pneumatic brake, with the new air-free Siemens Brake System the control of the brake is fully electrical (“brake-by-wire”). All piping and all pneumatic components for controlling the brake can be eliminated.
