@driskos1: A shunter losing traction while moving a heavy train. It experiences wheel slip because the steel locomotive wheels have very little natural grip on steel rails. A heavy load, or poor rail conditions (like wet weather or crushed leaf residue), can cause the locomotive's tractive effort to exceed the friction limit, forcing the wheels to spin rapidly in place. To counteract that, you can see the locomotive driver drop the power and let the locomotive travel forward very slowly until it passes this slippy and slightly inclined section of track. Once clear, it can speed up again. #trains #diesellocomotive #railway #heritagerailway #railfanning
