Problems in the application of the dowty retarder in the marshalling station and the adverse effects on the shunting operation

If there are problems in the application of the dowty retarder in the marshalling station, if it is not solved for a long time, it will have some undesirable consequences, which will have an adverse effect on railway transportation.

Because the dowty retarder is not well managed and maintained, or is often in a bad state, the dowty retarder installed on the line is gradually damaged and gradually reduced, resulting in a vicious circle. In order to ensure safety, the station had to seal the road, and the original 10-strand marshalling line was changed to 9 strands. The decelerating roof of one of the strands was added to the other strands, so that the station reduced the marshalling line and continued, and the marshalling line was reduced. There is no way at the station. Some lines use speed reducers, and some lines only restore iron shoes, which reduces the station's operating efficiency and affects the station's safety and the completion of transportation tasks. In the investigation, we saw this-a station, dowty retarder's turnout area decelerator (full roof scheme) is broken-one is removed, because there are no spare parts to supplement, no maintenance, there are very few decelerators in the turnout area, so we see The disintegrated train did not dare to pass the hump and had to take a detour, which had a great impact on the shunting operation.
