Title Pressure effects in railway tunnels
Bibliographic information Apr. 2000, Vol.31, No.4, p.10-17. Illus. 10 ref.
Abstract The severe pressure waves generated by high-speed trains travelling through tunnels may create severe discomfort, and - in extreme cases - ear damage in crew and passengers on trains travelling through these tunnels. Should there be a case of rapid decompression (e.g. if a window broke while the train passed through the tunnel), the health consequences may be even more serious. There do exist solutions, all of which costing money. Expensive solutions include changing tunnel configurations (larger tunnel cross-sections, installation of air shafts) or the trains themselves (complete pressure sealing of train compartments). Less expensive solutions involve the prevention of two trains passing each other in the tunnel and a general reduction in train speeds while in the tunnel.
