1. The turnout position of the main line of a single-track station is the position where both ends of the station open to different lines.
2. The position of the turnout at the entrance of the main line of the double-track station is the opening position of each corresponding main line.
3. The turnouts on the main line in the section and other turnouts on the main line in the station (except turnouts leading to the safety line and refuge siding) are located at the opening of the main line.
4. The position of the switch leading to the safety line and refuge siding is the position of the whole line of Yu 'an and refuge siding.
5. The positioning of other turnouts managed by the station shall be stipulated by the station according to the requirements of traffic safety, convenient work and scientific management, combined with specific conditions.

Turnout is a line connection that transfers locomotives and vehicles from one track to another. With turnout, the bearing capacity of the line can be fully exerted. Even if there is a railway, we can lay turnouts and make turnouts that are longer than the length of the train. Coal mine turnout manufacturers point out that turnout plays an important role in railway lines.
Each switch group consists of a switch, a forklift center, two guardrails and a fork pillow. Based on the lever principle, the wheel is driven by a long handle and enters the predetermined road along the opening direction. Positioning is a single switch, the train entering through the switch is positioning, and the curve is the reverse position.
In the process of writing, the common position of the switch is positioned, and the rarely used position is inverted. In fact, we usually set the positioning as a straight line and the reverse positioning as a curve. There are many kinds of railway turnout equipment, which ensure the safe operation of railway vehicles. This is because turnstiles usually have a short empty patio in the center of the rut, where the track is destroyed.
The two brake wheels and the track are used to make the train "go straight"-a hole in the track is called harmful space. At the same time, the turnout is connected by two small radius curves "S", so it is no wonder that the train swings from side to side. In order to improve the speed of the train passing through the turnout, reduce the discomfort of passengers and prevent the goods from moving, a larger turnout can be used.
