The terms "dynamic envelope" or "kinematic envelope" – which include factors such as suspension travel, overhang on curves (at both ends and middle) and lateral motion on the track – are sometimes used in place of loading gauge. The difference between the two is called the clearance. It is distinct from the minimum structure gauge, which sets limits to the size of bridges and tunnels on the line, allowing for engineering tolerances and the motion of rail vehicles. The loading gauge is the maximum size of rolling stock. In the past, these were simple wooden frames or physical feelers mounted on rolling stock. Compliance with a loading gauge can be checked with a clearance car. The devices ensure that loads stacked on open or flat wagons stay within the height/shape limits of the line's bridges and tunnels, and prevent out-of-gauge rolling stock entering a stretch of line with a smaller loading gauge. The term "loading gauge" can also refer to a physical structure, sometimes using electronic detectors using light beams on an arm or gantry placed over the exit lines of goods yards or at the entry point to a restricted part of a network. Containerisation and a trend towards larger shipping containers has led rail companies to increase structure gauges to compete effectively with road haulage. Over time there has been a trend towards larger loading gauges and more standardization of gauges some older lines have had their structure gauges enhanced by raising bridges, increasing the height and width of tunnels and making other necessary alterations. It varies across the world and often within a single railway system. The loading gauge restricts the size of passenger coaches, goods wagons (freight cars) and shipping containers that can travel on a section of railway track. Overview The London Underground utilises differing loading gauges: a Metropolitan line A Stock sub-surface train (left) passes a Piccadilly line 1973 Stock tube train (right). The specified amount of clearance makes allowance for wobbling of rail vehicles at speed. The difference between these two gauges is called the clearance. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses.Ī related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. Classification systems vary between different countries, and gauges may vary across a network, even if the track gauge is uniform. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Pictured is a London Underground Northern line train at Hendon Central.Ī loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads.
