Many people have seen and ridden railways and trains, but do not know much about railways. In fact, the railway is made up of various accessories and equipment, and with the booming development of the railway, the rail tie plate and equipment are also constantly developing. In order to ensure the safe operation of the train, the current rail tie plate and equipment must have the characteristics of high strength, good toughness and better fatigue resistance. In order to deepen our understanding of railway equipment and rail tie plate, our company will introduce several common railway equipment.

1. Connecting parts, because the railway is composed of various accessories, and the combination of components requires the use of various connecting parts. The parts that connect the ends of the two rails are called joint connectors. The part that connects the rail and the sleeper is called the intermediate connector, which is also the fastener we say. The joint joint allows the wheel to roll smoothly over the rail joint and keeps the front and rear rails working in harmony. The fastener can very well connect the rail and the sleeper together to form the rail frame, so that the two rail to maintain the correct relative position; Fasteners provide enough pressure to prevent the track from turning over and prevent the track from moving lengthwise.
2. Subgrade usually refers to the ballast (ballast) cushion layer laid under the sleeper and on the surface of the subgrade. The main function is to support the sleeper and disperse the huge load on the upper part of the sleeper to the uniform roadbed surface, thus greatly reducing the deformation of the roadbed. The ballast is a small piece of granite with a diameter of 20~70mm, and there is a gap and friction between the blocks to keep the track very elastic. Once the ballast loses elasticity, the load on the reinforced concrete sleeper will be greatly increased than the normal state.
3. Switches are line connection devices that transfer rolling stock from one track to another, usually laid at a large number of stations and marshalling stations. It is precisely because of the turnout that the traffic capacity of the railway line is fully utilized.
