The train consisted of 4 coaches and operated on a one mile (1.6 km) long track on the Depot grounds. 261 even posed next to Canadian Pacific's Holiday Train when it also visited the depot. It reprised its role as the locomotive for the "North Pole Express" at St. Paul Union Depot from 2015 to 2022, operating over two weekends each December.
A remaining section of the Aérotrain track near Saran 2006. The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917–1975) – and intended to bring the French rail network to the cutting edge of land-based public transportation.

Grades of 5% are not uncommon on them. Metros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds.

T gauge (1:450 or 1:480) is a model railway scale with a track gauge of 3 mm (0.118 in), referred to as "three-millimeter gauge" or "third of N scale."It was introduced at the Tokyo Toy Show in 2006 by KK Eishindo of Japan and went on sale in 2007.
Too tight a 'crest' curve could result in the train leaving the track as it drops away beneath it; too tight a 'trough' and the train will plough downwards into the rails and damage them. More precisely, the support force R exerted by the track on a train as a function of the curve radius r, the train mass m, and the speed v, is given by
