Due to various reasons, the phenomenon of "false top" of dowty retarder exists in various marshalling yards to varying degrees, and it is relatively hidden. It is not easy to be found if it does not pass the top by top trampling inspection during patrol inspection.

In particular, the occurrence rate of "false roof" of dowty retarder is higher when the service time is longer than that of overhaul period. For example, the retarder in the marshalling yard of Hengyang North railway station should be overhauled in 5 years due to the large traffic flow. But now, due to the lack of funds, it has not been overhauled in 7 years, and other reasons, the incidence of "false roof" of dowty retarder is on the high side.

The incidence of false dowty retarder is nearly 7%. As the number and distance of each track cloth top are determined strictly according to the design, the existence of "false top" of dowty retarder leads to the complete loss of its single top work effect, which seriously reduces the overall effect of each track dowty retarder work, and its harm is directly reflected in the process of vehicle sliding, when the vehicle is hung with a heavy coupler, the coupler or baffle will be damaged, and the vehicle rivets will be removed or even dropped.
