This report contains measurements on noise emission from the Swedish multiple unit denoted X60. The meaurements have been analyzed and used to prepare input data for the Nordic noise calculation methods for railway traffic noise NMT96 and Nord2000. The result shows that in a typical case the A-weighted noise emission per meter train is approximately 6 dB lower for X60 compared to the high speed train X2.

Measurements were also carried out for the multiple unit X40, but unfortunately the spread was too large and the number of data points to small to create valid input data for the methods. More extensive research is needed, and until better data is available it is recommended to use X2 input data as an approximation of X40 noise emission.
