Abstract (en)

[origin: WO8702949A1] An operation system for high speed underground trains, in which the stations are not directly situated on the railway lines but on branches that run parallel to the lines. The stations are hermetically sealed from the transport tunnels at their branching points during straight through traffic, so that the operation of the stations will not be disturbed by the shock of compressed air generated in the transport tunnels.
