AEORDYNAMIC MEASUREMENTS MADE BY THE DB RESEARCH INSTITUTE IN MUNICH IN THE HEITERSBERG TUNNEL ON SWISS FEDERAL RAILWAYS

AERODYNAMISCHE MESSUNGEN DER BUNDESBAHN-VERSUCHSANSTALT MUENCHEN IM HEITERSBERGTUNNEL DER SCHWEIZERISCHEN BUNDESBAHNEN

With increased train speeds, problems of aerodynamics are arising. The question of running through tunnels is of particular relevance. Aerodynamic measurements were made when two trains passed each other in the CFF's Heitersberg tunnel. The express train (maximum speed 210 km/h) was composed of a DB 103 locomotive and 3 DB dynamometer coaches, and the slow train of the CFF Re 4/4 II locomotive and 7 coaches. The article describes the research programme and explains in detail the pressure rates selected on a number of runs.
