0 a transport system that uses cables under the road to pull passenger vehicles up steep slopes -- 缆索铁路
It can be considered as a specialised type of cable railway.
By the 1820s a number of proposals had been made for canals, and cable railway had been proposed costing upwards of 500,000, but all these ideas had come to nought.
In order to accommodate intermediate levels, turnouts were used to allow wagons to leave and join the cable railway part way along its length.
The concept was similar to the cable railway system but with pistons suspended beneath the railcar.
Cable railways generally have two tracks with loaded wagons on one track partially balanced by empty wagons on the other, to minimise fuel costs for the stationary engine.
However, the unsuitability of cable railways for passengers became clear within a few years.
The cable railway line descends 415 metres through sandstone cliffs, via a rock tunnel with a maximum gradient of 52 degrees.
Many cable railways connect to conventional adhesion lines at their top and bottom, allowing trains to be lifted from a lower line to a higher one.
