This report of tractive resistance data from a British Transport Commission bulletin in terms of lb. per ton yielded a dimensionless drag of 0.6 to 0.9 and rolling resistance values of 3.5 to 4 lb. per ton for various diesel locomotives. At speeds above 10 mph and particularly in the speed range of 20 to 80 mph the values of r or R are influenced by the component proportional to (V/10) and not by C(sub d) and the (V/10(super 2)) factor. This suggests that the effect of transmission and coupled axles action is of considerable influence.
