How to Electrify a railroad

Ive thinking about how to respond to your turn out catenary problem and this is how I would deal with the solution.
There are some rules in catenary construction
1. Always put a pole at the begining and end of a curve.
2. Poles are closer together on curves.
3. In inclined catenary theres always a transition span between tangent and curved track
4. The messenger wire in inclined catenary appears straight while the trolley wire is curved

Take a look at this diagram... taken from a larger 3d plan of my layout. I design all my catenary on the computer before I build it .. Take note of the transition sections at the begining and end of the curve.

usually there arent any turnouts where theres inclined catenary. If there are turnouts the catenary is simple and 90 degrees above the track. The catenary is curved or aligned with pull off wires on smaller poles. I managed to get around the switch on a curved tricky situation using a triangular bracket attached to a wire off a pole to make a divergent inclined catenary wire to create the wire crossover junction above the switch.. If you can understand that
