The Falns is a four-axle freight wagon - a so-called self-unloader - that is used for coal trains. The wagon has flaps on the side, so that the load can be released using gravity, which means that the load flows through the flaps from the load space. The wagons are open at the top, so that the load can be collapsed from above.
The Falns type designation has the following meaning:
F = open dump truck
a = with 4 axes
l = self-unloading bulk wagon with opening roof on both sides at the same time
n = total weight> 60 t
s = maximum speed 100 km / h
