Thank you."As you probably know, a slower moving train will make fewer axle revolutions over the same distance a faster moving train does." Due to increased wheel slip/lower adhesion? A smaller wheel makes more revolutions than a larger one to go the same distance. Hence an axle mounted odometer is made inaccurate by mounting it on a wheel for which it is not calibrated. But the same wheel at different speeds? Are my proposed above reasons the cause? |
