Catenaries are very complicated to model. However, you should pay attention to details in a gauge 1 layout with overhead contact line that only become apparent at second glance.

The new Sommerfeldt overhead contact line for gauge 1 should be somewhat simplified and inexpensive. How good are the components and how do you differ from the Wunder product range?

The Sommerfeldt overhead contact line for gauge 1 has gone into mass production and is available. But before we get to grips with the model, I would like to convey some facts about the original and outline the limits in the model.
