X-Wagen

In close collaboration with Siemens Liebherr developed and produces a compact, closed, electrohydraulic brake actuator including all the components necessary to build-up and release the brake force as well as local control. The Siemens braking system demonstrates its advantages on the new modern underground railway in Vienna.

Products on board

Electro-hydraulic brake actuator

Special features

The brake actuator is integrated in the bogie in the same installation space and has the same mechanical interfaces as the conventional pneumatic brake caliper. This brake actuator meets the highest safety requirements and Safety Integrity Levels up to SIL4 and also the latest rules and regulations for safety verification. Using the air-free brake results in a number of benefits on car-level, including reduced weight and reduced effort for installation and commissioning of the brake system. In addition, installation space that was previously required for the air brake components can now be used for other subsystems.

FLIRT electrical multiple unit

Liebherr supplies to Stadler Polska series-produced propane-based HVAC systems for FLIRT trains (Fast Light Intercity and Regional Train).

Autorail à Grande Capacité (AGC)

HVAC units developed and manufactured by Liebherr are integrated in SNCF’s Autorail à Grand Capacité (AGC) trains by Alstom, which are operated in the Occitania Region (France). The air-conditioning system based on environmentally friendly air cycle technology uses only ambient air as a coolant instead of conventional chemical refrigerants.

Etihad DMU

The saloon and cab HVAC units are installed on high-speed diesel multiple unit trains manufactured by the Chinese company CRRC. The trains are operated by Etihad Rail, the national railway company of the United Arab Emirates (UAE), on UAE’s first national rail network.

CTA 7000

Liebherr supplies level control systems for its customer CRRC Sifang America. These are installed in the 7000 series rail vehicles operated by the Chicago Transit Authority (CTA).

Twindexx Swiss Express

With its electro-hydraulic actuator, Liebherr is on board of the Alstom Twindexx, the flagship of SBB's long-distance services.
