The wheels of railway vehicles have a special profile on their running surfaces. On the one hand, they have a flange on the inner side so that the wheels remain on the rail. On the other hand, the running surfaces also have a special profile so that the wheels run safely and quietly on the rails. From time to time these profiles have to be re-turned because even metal wheels or tyres can deform over time. This was also the case with our locomotive 50 3570.
On 10.12.2017 we therefore sent her, towed by a diesel locomotive on her way to Neustrelitz, where there is an underfloor wheel-turning lathe. Here the whole locomotive is driven onto the lathe and the wheels are turned in an installed condition by the lathe's powerful electric motors. Then a turning tool is driven against the wheels and metal layers are removed from the running surfaces of the wheels until the profile is right again. The pictures show the transfer of the steam locomotive to Glashütte and Pritzwalk and the video shows the operation on the lathe.
