Abstract: A track installation for vehicles of a transport installation comprises a track supporting the vehicles at their vehicle carriages and possessing an inbound side and an outbound side for the vehicles. A conveyor is operatively associated with the track and contains entrainment members for entraining coaction with the vehicles. The track constitutes a generally or essentially horizontal track structure and extends along the complete length of the conveyor. Vehicle stops defining stop or parking positions for the vehicles are distributively arranged along the track. Each stop is provided with an actuation element and each stop or parking position has a vehicle sensor as well as an interrupter for disabling the entrainment of the there parked vehicle by the conveyor. The vehicle sensor of each stop or parking position is connected with the actuation element of the stop and also with the interrupter of the preceding or upstream located stop or parking position viewed in the vehicle conveying direction.
