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 ...
Track gauge. Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces [1] in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the ...
The car was repurposed in 2020 with a LiDAR Laser Measurement System. #10002 Corridor Clipper, an Amfleet I-based track geometry car. It is periodically attached to the end of a diesel or electric revenue-running train or is hauled by a locomotive only. The car previously had a special pantograph that was used to test and measure overhead lines.
Ackermann geometry. The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. It was invented by the German carriage builder Georg Lankensperger in Munich in 1816 ...
Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked ...
In automotive engineering, toe, also known as tracking, [1] is the symmetric angle that each wheel makes with the longitudinal axis of the vehicle, as a function of static geometry, and kinematic and compliant effects. This can be contrasted with steer, which is the antisymmetric angle, i.e. both wheels point to the left or right, in parallel ...
The track geometry car typically checks each stretch of track about 6 times a year; the car is manually operated, and there are no plans to automate inspection of the track geometry, which is done manually with the help of high-tech equipment aboard the car. [53]
