[0002] The subway is a type of urban rail transit system. It refers to a high-speed, high-capacity, electric-powered rail transit system built in cities. Trains run on fully enclosed lines. Lines in central urban areas are generally located in underground tunnels, while lines outside the central urban area are generally located on viaducts or on the ground. With the continuous development of rail transit, more and more cities are gradually building rail transit to solve traffic congestion problems. The rail system is an important component of rail transit. The current rail system mainly consists of subway tracks and track pads used to support the subway tracks.
