The Wettex-sleigh at first had a tendency to derail, especially in the very back of the long tunnels... That was remedied with a small modification of the couple on the locomotive. Right this poor pierced DB218-lok is thus doomed to a lifetime cleaning service ...
Current consumption at eight large wheels means forgiving running behaviours. The locomotive is able to muddle around in a rather overgrown path. A few turns with the sleigh and the traffic goes smoothly again.
The Cleaning Express during emergency! By far the nicest cleaning chore at home!
