Summary

In this project acoustical measures at three modern diesel locomotives are presented. Due to additional rebuilding of vehicles to a small amount the noise limitations of the TSI-Noise 2006 also in rolling stock can be kept. The project is realised with the railway operator HVLE Havelländische Eisenbahn and is promoted as a contribution to the conversion of the Directive 2002/49/EU within the scope of the environmental innovation program of the federal ministry for the environment.

The BlueTiger is a six-axle freight train locomotive with 126 t heavy weight, supplied by a 2.5 MW diesel power unit and moved by electric traction. For the classification in categories of the sound sources the sound intensity was measured along the standing and onto the moving vehicle. Mainly fans and auxiliary aggregates are responsible for the excess of the noise limit values. The diesel engine in the middle of vehicle is sound insulated by lockable doors. The high-frequency sound parts of traction fan and electro dynamic brake can be reduced by absorption and insulation.
