• Abstract:
  The scope of this study has encompassed an evaluation of fourteen yard speed control devices, an identification of four generic speed control systems, a qualitative assessment of the four systems, and finally a quantitative analysis of three hypothetic yards each employing a system that is considered promising. These three systems are (1) the advanced clasp retarder system, (2) the quasicontinuous control system, and (3) a hybrid system incorporating quasi-continuous control. No ranking of these three systems is possible because each has its advantages and disadvantages; and one system may be more suitable than the others under a particular circumstance
