Describe the solution you'd like
I'm a little frustrated, that there is no ability to get rails path map. I have a big railway system on my multiplayer server (about 10000~ railblocks) and have no ability to create public railway map

Describe alternatives you've considered
I have tried just to draw paths on DynMap, but this is a very long process. Even if I'll write an addon for the dynmap to collect path information and build the paths on the map, this wouldn't be a good solution, because I've branches with routing not a single railway line.
Additional context
I wish that there'll be a method to export all path and routing information to JSON, or integration with dynmap, or ability to view path map on embedded to mod GUI.

Thanks for attention.

If I ever rework the signal system so that a graph of the rail system gets built (based on the charge network), we would get this for nearly free. Would just need a way to render the information then.
