I would say that is almost a 'lift' as it is pulled by a cable and doesn't drive itself. Similar to cable operated wagon lifts, which is what I assume it was originally. No geared centre rail I notice.Hopefully it has suitable failsafe gear.
Narrow gauge Francophile interested in 1m, 60cm,50cm , 40cm and smaller gauges . Build in scales from 1/6th to 1/24th. Also 1/32nd and 1/35th using 16.5mm track to represent 50cm and 60cm gauges. http://www.rue-d-etropal.com
