The Téléo cable car in Toulouse, France, is like no other in an urban setting.

This technology was born in and is mostly predominant in ski resorts. Many cities in South America started installing "metrocable" systems in the past years, that repurpose the classic 8-10 seater gondolas for urban use, and there is a similar project under construction in Paris suburbs.
But this one is unique because of its 3S technology a.k.a. the XL, more robust version of a gondola lift. The Téléo line is actual public transport and belong to the Tisséo, the Toulouse transit system that comprises two subway lines, one tram line, a bus network and this aerial line. The base fare of the network is sufficient to ride and transfers are included.
The Téléo line has three stops in total; the intermediary stop pictured above provides direct access to a local hospital on a hill. There is a similar installation in Koblenz, Germany, although more aimed at tourists.
3S means "3 seile" in German, literally "three ropes". Two are stationary and act as rails on which the suspension carriages roll. The third one is in movement, hauling the vehicles along the line.
The advantages of the 3S technology, in comparison to a standard gondola installation you can find in southern American cities and many ski resorts, are:
- Greater resistance to winds: a standard ropeway would have to close down for safety while this 3S can keep running through 100 km/h winds
- Higher cruise speed
- Higher maximum flyover height
- Longer distance between two adjacent support towers: the Peak 2 Peak in Whistler, Canada, has more than 3 km of hanging distance between the two furthest-apart towers.
- Bigger gondolas that can hold more passengers
A single-rope gondola system would require more towers along the route and a lower maximum flyover height, mostly due to laws regarding ropeway installations that take into account emergency situations and the ability to rescue passengers stuck on the line in case of traction power failure.
Even in ski resorts, 3S systems like this one are quite rare and only present in the most affluent ones such as Zermatt or Grindelwald in Switzerland.
Speaking of the gondolas...

This represents the scale of the gondolas, which are quite massive for a continuous loop system. One gondola enters the station every 90 seconds during rush hour.

Inside, there is enough seating for 20 people and a space for wheelchairs, plus standing room. A passenger information display is provided to show position along the route.
The local transport planning authority has started proposing ideas about extending the route, but it is still in the early discussions.
