The noise emission of the Swedish X2 high speed train has been determined at 7.5 m and 25 m distances at speeds between 130 and 200 km/h. The measurements were carried out according to ISO/DP 3095 and the train was in regular operation between Stockholm and Gothenburg. The measured data have been used to supplement the Nordic prediction method for railway noise with a new train category, the high speed train. The results indicate that the noise emission of the X2 train at 200 km/h is less than that of the older trains in InterCity and CityExpress traffic at 160 km/h. For X2 the maximum noise emission occurs in the 2000 Hz octave band compared to the 1000 Hz octave band for conventional trains. The Swedish X2 high speed train started operation between Stockholm and Gothenburg at the beginning of 1990. It is designed to operate in speeds up to 200 km/h.
