The current full revision of the TSI Noise includes consideration of a second step of noise limit values for railway cars, taking into account the developments in technology.

    The state-of-the-art of noise emissions of European rail vehicles was determined on the basis of a collection of TSI Noise data of railway cars. From these data the state-of-the-art of the noise emission of European railway cars was derived.

    The results indicate that the most of the current limit values for stationary noise and starting noise are significantly above the state-of-the-art noise emission performance of European railway cars. With regard to pass-by noise, the state-of-the-art and the current limit values are closer together. However, in the case of freight wagons and electric multiple units, the current limit values are approximately 5 dB above the state-of-the-art.

    It would therefore be reasonable to adjust the limit values to the state-of-the-art within the scope of the TSI Noise revision.

    As a result of the revision process, the scope of the TSI is extended to a much wider network, a continuous limit curve for freight wagons is defined in the TSI and new requirements for stationary noise were introduced, which shall help to handle problems with stationary vehicles. For most vehicle categories the redefined limit values are still significantly above the state-of-the-art.
