CHEMICALS TO IMPROVE RAIL ADHESION

The chemical spraying method developed by British Railways offers a promising solution to the wheel slip problem, and it is significant that there is now a proprietary spraying device known as the P and M Maxi-mu. An important and essential feature in the application of the chemical spray method is the making of adhesion surveys, using the tribometer, of portions of the track where wheel slip is serious prior to the installation of distributors. This enables the most effective positions for distributors to be determined. Spreading of the chemical fluid is actually performed by the train wheels. During 1964-65 extensive tests of ethyl caprillate were made, and it is now established that this is the most generally satisfactory of all the chemicals which have been so far tried.
