Adhesion remedies - A summary of recent development work on lineside fluid applicators (TM-TRIB-8)

During 1974, a number of liquid systems were tested for their ability to increase wheel-rail adhesion when applied to the railhead by trackside applicators. Only ‘Syton’, which is an aqueous colloidal suspension of silica, consistently increased the wheel rail adhesion under the test conditions. It was decided therefore that a...
