Abstract

An exhaust-gas offtake for a track-guided vehicle propelled by combustion-energy, the exhaust gas being led into a force-ventilated waste gas duct located above the vehicle, which is anchored to the roof of a tunnel along the route followed. The exhaust pipe of the vehicle extends vertically through the vehicle interior, up to a point above the roof, and is surrounded by a protective tube. A collecting funnel is located on the vehicle roof, which funnel overlaps the end of the exhaust pipe, possesses a transfer pipe with a boat-shaped cross-section and, pivotably mounted on suspension elements, is resiliently directed into an upwards-pointed position. This arrangement enables small horizontal and vertical movements of the vehicle body to be compensated in relation to the tunnel waste gas duct.
