Prospects for the application of dowty retarder in stations

As we all know, the general dowty retarder is mostly used in the hump speed regulation system in the marshalling yard. Can the dowty retarder be used on other lines? According to "the workmanship of the dowty retarder is realized by the opening and closing of the internal speed valve plate, adjust the opening amount of the speed valve plate and replace the support spring of the speed valve plate, which can be adjusted The characteristic of the "critical speed of the dowty retarder", it is envisaged to install the dowty retarder on the line before and after the loading point of the large-slope loading loop or before and after the track scale to assist the train to brake to reduce the civil engineering of the line. According to this idea, through analysis of examples, it is concluded that the dowty retarder can also be used on the line where the slope in the station is large and the auxiliary braking of the train is required, and its application prospect is broader.
