DOWTY OLEO RETARDERS GIVE STEADY CONTROL

The Dowty system of wagon control is to be tested at Kazerne Marshalling Yards and, if successful, it could be applied to any new marshalling yards the SAR will construct. Since the introduction of the Dowty Oleo (gas-oil) retarder in 1971 two new yards have been constructed on the all-retarder principle--the first with 19 sidings is fully operational in Britain and the second, with 31 sidings, at Forrestfield, Western Australia, involves some 7,500 retarders and is also in operation. The Dowty Oleo retarders will also be used at the proposed Musashino yard in Japan and in various private installations. For America and other markets, where heavy tare weights permit greater retarder thrust without danger of derailment, a high duty unit is undergoing trials and will be available later.
