QUASI-CONTINUOUS SPEED CONTROL IN GRAVITY YARDS USING THE DOWTY RETARDER

Interest in the use of multiple hydraulic retarders to regulate the speed of wagons in hump yards at frequent intervals rather than at a few discrete points in growing steadily. After Westrail had installed Dowty retarders in the new Forrestfield yard near Perth, and SJ set out to equip Helsingborg yard throughout with ASEA screw retarders, SBB decided to make partial use of Dowty retarders in Zurich-Limmattal which is still under construction. Complete mathematical simulation of the behaviour of cuts in a yard equipped with quasi-continuous speed control is as essential for the designer as in the case of classical yards.
