Division 7.4.2 Boundary characteristics linked to exterior noise (BP17)

It is recommended that in the case of rolling stock to be ordered after 1 January 2005 or to be put into service after 1 January 2008, Section 4.1.8 of this TSI is applied with a reduction of 2 dB(A) at a speed of 250 km/h and 3 dB at speeds of 300 km/h and 320 km/h. In the case of 350 km/h, a reduction of 3 dB(A) should be striven towards.

This recommendation will serve as a basis for revising Section 4.1.8. in the context of the TSI revision process.
