A cable railway installation has an endless conveying cable extending between terminal stations. Transport vehicles, such as chairs or gondolas, are coupleable to the conveying cable. In the two terminal stations the cable is guided over headwheels and, in optionally provided intermediate stations, it is guided over diverting pulleys, diverting rollers or the like. The transport vehicles entering the terminal stations are uncoupled from the conveying cable, conveyed through the stations by guide tires and then coupled to the conveying cable for exiting the stations. A load bearing structure, which carries components such as the headwheels, diverting pulleys and rollers, and the guide tires, is borne by at least one support disposed centrally between the paths of motion of the transport vehicles. An ascent leads up to the load bearing structure. The support carrying the load bearing structure is formed with a through passage through which the ascent is routed.
