18-673, a Class 18E Series 2 locomotive, is in charge of this "Python" - a load of 65 X CAR Wagons (Ore / Coal), in this case these are empties, and has just completed the tight righthand swing under the road bridge into Dargle Station in the KwaZulu Natal Midlands, for the run up the hill to Lidgetton. This train is probably bound for Newcastle in Northern KwaZulu Natal to collect coal for the factories in Cato Ridge.
