The scheme of installing the dowty retarder on the line

If the dowty retarder are continuously arranged in groups on the first section of the line, considering that the braking force of a single dowty retarder occupies a very small proportion in the entire system, even if the braking ability of a single dowty retarder is lost, the impact on the entire system is very small. Therefore, the continuous installation of dowty retarder in groups on the line can be used as an external force to consume the potential energy of the train, achieve a certain degree of deceleration, achieve the purpose of auxiliary braking, and ensure the safety of loading operations.

According to the structure principle of dowty retarder, the speed of dowty retarder can be adjusted within the allowable range of the speed valve plate opening and the support spring to meet the needs of train operation. Therefore, from theoretical analysis, it is technically feasible to install the dowty retarder on the line before and after the loading point of the steep slope and before and after the rail scale; from the analysis of the structural performance of the dowty retarder, it can ensure the safety of vehicles or trains in a fixed speed range.
