Abstract (en)
[origin: GB2470974A] The invention provides a railway tunnel ventilation apparatus which significantly enhances the piston effect of an underground train moving a column of air from a single track underground tunnel into a station platform area where it is naturally but indirectly replaced by fresh air from the surface. The apparatus comprises a ventilation car V having the same cross-section as a train carriage 100. An onboard air curtain generator draws air from both ends of the car V and ejects it as continuous air curtains extending in use from the outer periphery of the car V to the tunnel internal surface. The air curtains act as a barrier to air flowing past the car V in the space between the carriage and tunnel, so that the air curtain assists in the driving of a column of air ahead of the train.
