A numerical procedure for the rapid prediction of the compression wave generated by a high-speed train entering a tunnel was presented and validated by Howe et al. . The method was devised to deal principally with compression wave generation in long hoods typically of length ~10 times the tunnel height and 'vented' by means of a series of windows distributed along the hood walls. Hoods of this kind will be needed to control wave generation by newer trains operating at speeds U exceeding about 350 km/h. In this paper experimental results are presented and compared with predictions in order to extend the range of applicability of the numerical method of Howe et al. (2006) to include short hoods with lengths as small as just twice the tunnel height (the situation for most hoods currently deployed on the Japanese Shinkansen) and for U as large as 400 km/h.
