1-d Calculations of Pressure Fluctuations Outside and Inside a Pressure Sealed High-Speed Trainset Travelling through Tunnels

Following the setting-up of a TRANSAERO database based on both full-scale measurements- conducted with an ETR 500/92 trainset in a tunnel located in Italy on the Diretissima high speed rail link- and 1/25th measurements -conducted on the Moving Model Rig (MMR) in Derby, UK-the SNCF Research and Technology Department undertook the validation of the TRANSTUN one-dimensional computer program.
