Several track designs that only serve as decoration, e.g. in a city or on an adventure map. You can see a straight line, a 90° curve with the same shape, and a stopper for locomotives.

Here is the first "type of rail": An old rail, like in the wild west, where coal locomotives still ran over it:

The second type of track is supposed to represent a modern standard locomotive guide from the 2nd millennium:

The third design is a futuristic 1-rail maglev design, I mainly focused on bright lighting and good design. You can also run these rails on large bridges over cities:

The 4th design is supposed to represent tram (streetcar) tracks, I built this on a one way street for better visibility, but for a big city of course expand to 4-5 lanes! 🙂

Note: To see how the lighting affects the rails, I took the screenshots at night. I hope you don't mind, because you can see everything. I designed the designs myself and built them myself, but I can't 100% assure you that I was the first to build it this way.
PS: I hope you guys like my idea 🙂 .
