BEHAVIOUR OF THE METAL OF THE RAILS AND WHEELS IN THE CONTACT ZONE--ENQUIRY INTO THE PROBLEM OF SMALL DIAMETER WHEELS

This report summarizes the responses to an enquiry into the effect that a reduction in the diameter of wheels would have on the behavior in service of the rails and wheels. Information was collected on the subject of P/D ratios (P = load per wheel in tons, D = diameter in meters) and includes an analysis of tests carried out by the U.S., Russia, Germany, the British and the French. Very different values of P/D were found, depending on the railway and especially on the type of steel in the rails.
