For those that might not know where all the relevant switches are, I thought I'd describe where to find them below. Locomotive GPR-selector. If the train you are driving, as described here, has the brakes in "all G", then the locomotive brake has to be changed from the default position of P to G. This selector switch is found at the wall behind the drivers seat, as shown below. Wagon brake setting selectors On Nahverkehr Dresden the freight trains are already set up automatically with the wagons in their correct brake setting, but in the future there might be trains that don't have the brakes set correctly. In this case you can find them on the under carriage of the wagon as shown below Freight wagon Empty/Load switch Some wagons have manual Empty/Load selectors that change the brake force of the wagon. This selector should be in the correct position depending on the wagons weight but if you need to change this for some reason then you can find them on the under carriage of the wagon (if the wagon has this sort of switch) as seen below These switches should be in the "Empty" position if the wagon weight is below the lower of the 3 printed numbers and it should be in the "Full Load" position if the wagon weight is above the same number. The two top numbers are the braked weight in corresponding position.
