A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
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.
Another downside is that the repulsive system naturally creates a field in the track in front and to the rear of the lift magnets, which act against the magnets and create a form of drag. This is generally only a concern at low speeds; at higher speeds the effect does not have time to build to its full potential and other forms of drag dominate.
A suspension railway is a form of elevated monorail in which the vehicle is suspended from a fixed track (as opposed to a cable used in aerial tramways), which is built above streets, waterways, or existing railway track. The Memphis Suspension Railway
Rail vehicle wheels are usually mounted on a solid axle, so they turn at the same speed.When a vehicle turns the outer wheel has to travel further than the inner wheel. On a road vehicle, this is usually achieved by allowing the wheels to move independently, and fixing the front wheels in an arrangement known as Ackermann steering geometry.

Side friction wheels keep the train centered in the track, avoiding derailment. The final set of wheels in the assembly are known as running wheels, road wheels, or tractor wheels. Running wheels are typically the largest set of wheels in the assembly, and roll on the top of the rails. These wheels bear the weight of the train.
