Products on board
Propane-based heating-, ventilation- and air-conditoning system
Technology
This design marks a special milestone for Liebherr as the company is supplying for the first time a series-produced HVAC system using propane. The technical concept considers all relevant safety requirements. Propane as a refrigerant offers a natural alternative to conventional, environmentally harmful refrigerants. In addition, the system is easy to service and guarantees rail operators a reliable product solution with minimal down time.

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.

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.
