Thank you for your opinion on the power rail. They were built by me.
On the subject of performance:
In order to investigate the influence of power rails on the performance, I have already tested this in advance. I equipped a map once with all 3 power rails available in the base content, once with overhead power lines and once without any power supply. Obviously, the performance was highest without power supply. However, when looking at the FPS, the conductor rails performed better than when using the overhead line. For Lotus, the number of polygons is less important than the number of individual objects (such as catenary poles).
Due to the technique of the map editor, the conductor rails are packed together with the tracks and sleepers into a fixed mesh. In terms of polygons, they belong together. Therefore, there is no problem here.
If you have noticed a problem regarding the performance in comparison to one of your maps, you are welcome to send it to me so that I can understand this problem myself.
On the subject of the model:
In Berlin, where these conductor rails are used, there are places in the network where the corresponding faces are needed in order not to look into the void. For example, viaducts or certain turnarounds on the line. It is also planned to be able to walk around in the first-person perspective later on, where you can see the conductor rail from a different perspective.
All in all, a holder of the conductor rail has less than 100 polygons and a piece of the conductor rail itself less than 75 polygons. In today's world, however, this is perfectly tolerable. Other factors have a much greater influence on performance, such as the textures.
Finally, no one is forced to use my conductor rail. Especially since it is only used in the Berlin underground in this design. (As far as I know)
If you don't like this variant, feel free to build your own and use it.
