The dowty retarder will bring those adverse effects on the shunting operation

If the problems existing in the application of dowty retarder in marshalling yard can not be solved for a long time, it will produce some bad consequences, which will bring adverse effects on railway transportation.

Because the management and maintenance of the dowty retarder is not good, or it is often in a bad state, the dowty retarder installed on the line is gradually damaged and reduced, resulting in a vicious cycle. In order to ensure safety, the station has to close the track, from the original 10 strand marshalling line to 9 strands, and add the dowty retarder of one track to other tracks, so that the station reduces the marshalling line and continues to reduce the number of marshalling lines. There is no way for the station to reduce the number of marshalling lines. One part of the lines use deceleration roof, and the other part of the lines only restore iron shoes, thus reducing the operation efficiency of the station, It affects the safety of the station and the completion of the transportation task.

In the investigation, we can see that the dowty retarder in the turnout area (full roof scheme) of a station is broken, one is disassembled and one is disassembled. Because there is no spare parts to supplement and no maintenance, there are few dowty retarder in the turnout area, so we can see that the disassembled train does not dare to pass the hump, so we have to move back to the line, which has a great impact on the shunting operation.
