REDUCING FLANGE-WEAR ON BOGIE LOCOMOTIVES

The phenomenon of relatively rapid flange-wear on sharp curves with the bogies of Bo-Bo and Co-Co locomotives must be accepted pending the results of further research into the reduction of bogie weight and unsprung weight, the height of the bogie centre of gravity, different relative speeds of the axles and motors, weight transfer, etc. Flange or rail lubrication using a lubricant matched in viscosity to suit the ambient temperature lengthens the flange life from six to nine times, this factor varying according to the tire steel used. A change from tires of "D" steel to those of 70-ton tensile steel alone can increase flange life by as much as three times. A combination of lubrication, hard tires, and the fitting of a centralizer linking the movement of the two bogies and which is capable of drastically reducing flange forces on curves, will improve flange life by 12-15 times.
