Liebherr-Transportation Systems will be the supplier of spare parts for the regular, specified and comprehensive overhaul of the CTA’s electro-hydraulic level control systems featured on its 5000-series heavy rail vehicles. This includes all maintenance and wear parts to be replaced in the 714 hydraulic units as well as the 2,856 level control actuators.

“We are very happy knowing that our quality and know-how will play a role in the CTA continuing to operate their vehicles safely and offer their passengers in the Chicago metropolitan area the highest level of travel comfort,” states Wolfgang Böttcher, Director Customer Support, Liebherr-Transportation Systems GmbH & Co KG.

Safety and comfort

The electro-hydraulic level control systems for the heavy rail vehicles were delivered by Liebherr to Bombardier Transportation for installation in the bogies of the cars. The system adjusts the carriage body of the vehicle so that the floor height corresponds to the height of the train station platform. Four hydraulic cylinders are activated per vehicle, which position the carriage body until the exit edge matches the height of the platform. This makes boarding and exiting for all passengers considerably easier; particularly for those with limited mobility, passengers with wheeled luggage and families with prams and other accessories for small children.
