The "InnovTrans 2004" show in Berlin is the first to show a technical solution for silent rail transport. This is a rotating chassis car, called LEILA-DG, which is presented as lighter, quieter and less worn than current solutions. An electronic monitoring and diagnostic system also increases productivity. The wagon was developed by a Swiss and German consortium, with financial support from the German Ministry of Research and the Swiss Federal Environmental Agency BUWAL. The German Environmental Agency also took part in the project.
The German Federal Government regards rail freight as a significant challenge to move towards "sustainable mobility". The goal is to double the volume of goods transported on the rails between 1997 and 2015. One of the requirements to achieve this is the strong reduction of noise. Freight transport is mainly at night, and freight wagons are among the most noisy. The innovations incorporated in the new LEILA-DG wagon reduce noise pollution by a factor of 10 compared to cast iron braked wagons, and by an 4 factor compared to already soundproofed wagons equipped with synthetic material brakes.
The wagon is presented to the public for the first time at the "InnoTrans" show in Berlin from 21 to 24 September 2004.
