FUNICULARS

A funicular s a transportation system that uses cable-driven cars to connect points along a steep incline. By definition, a funicular uses two counterbalanced passenger cars attached to opposite ends of the same cable, which is looped over a pulley at the upper end of a track. 
 A funicular's two cars move in concert: as one ascends, the other descends simultaneously, an arrangement that distinguishes a funicular from other cable-guided transportation systems—e.g., a single-car inclined elevator. 
The term funicular derives from the Latin word funiculus, the diminutive of funis, meaning 'rope'.

Here is the Thonon-les-Bains's funicular.

Pneumatic brake system 

Pneumatic brake system :

The air compressor is driven by the engine either by crankshaft pulley via a belt or directly from the engine timing gears. It is lubricated and cooled by the engine lubrication and cooling systems. Compressed air is first routed through a cooling coil and into an air dryer which removes moisture and oil impurities and also may include a pressure regulator, safety valve and smaller purge reservoir. As an alternative to the air dryer, the supply system can be equipped with an anti-freeze device and oil separator. The compressed air is then stored in a supply reservoir (also called a wet tank) from which it is then distributed via a four-way protection valve into the primary reservoir (rear brake reservoir) and the secondary reservoir (front/trailer brake reservoir), a parking brake reservoir, and an auxiliary air supply distribution point. The system also includes various check, pressure limiting, drain and safety valves.
