ADHESION OF LOCOMOTIVES FROM THE POINT OF VIEW OF THEIR CONSTRUCTION AND OPERATION. USE OF SAND TO IMPROVE ADHESION

As sanding is the oldest and most widely-used method of improving the coefficient of friction between wheel and rail, an examination was made of studies carried out recently by several railway administrations on aspects of sanding. A questionnaire was also prepared and sent to all the ORE member-administrations, to summarise current practice on the following aspects: Quality and grain-size of sand used, Specifications of sand supplied to administrations, Treatment of sand, Handling of sand, Technical data on sanders used, and Rate of delivery of sand. From the information given, recommendations were made for obtaining the best results from the use of sand for increasing adhesion.
