If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys that simply allow the cable to change direction. While one car is pulled upwards by one end of the haul rope, the other car descends the slope at the other end.

Track ballast
Track ballast should never be laid down less than 150 mm (6 inches) thick, [4] and high-speed railway lines may require ballast up to 0.5 metres (20 inches) thick. [5] An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions, overloading the soil causes the track to sink, usually unevenly. [6]
