Date 2006-09-07 Abstract The contribution deals with numerical solution of a complex problem of aerodynamic loads evoked by a train motion while entering and passing through a double track tunnel. The train set consists of an electrical loco and three coaches. The loco model shape closely corresponds with a real three-system electrical locomotive developed and produced by KODA. The train performs a straight movement of 200 km/h speed rate. The main goal of the contribution is to monitor both the train motion aerodynamic effects on environment (tunnel wall surface) and backward effects of surrounding objects especially on loco body. Most of the results represent time variations of pressure, aerodynamic drag and velocities monitored both on tunnel and loco surfaces and in specified locations in the domain. Some of the values computed are compared with admissible limits published in adjacent standards.
