The purpose of ASEA’s trip to the Southern Pacific Railroad was to introduce ASEA’s classification yard equipment to the railroad. ASEA’s equipment consists of: Hydraulic retarders used in a quasi-continuous control design, and Cable wagon-hauling system for classification tracks. The cable wagon-hauling system is used primarily in yards with conventional clasp type retarders. It was not discussed extensively at the meeting. However, the spiral, hydraulic retarder was discussed at length. The paper compared ASEA’s design to the Dowty retarder with pros and cons; and describes in detail the technical implementation requirements for the ASEA screw retarder system.
The first step to improving the performance of retarder control algorithms is to conduct an exhaustive study of existing algorithms. Retarder control ...
The basic building blocks of a conventional retarder control system are described from a generic-functional viewpoint. The central function of a retar...
