Hey, nice project you have here. Let's keep this clear, I am not going to actively participate, sorry. I am starting to be busy with whatever (a new) university is going to bring me in the near future, besides that, I have nothing meaningful left to do in TFC, everything is achieved.
I have nothing against a railway to Elba, except for that I think it's not worth the effort (for me). I have already stopped building a road to that place, mostly because I fail to get active people in there, Elba is a ghost town. However, feel free to ask SuperSausage2 for materials and/or help, he is in charge of stuff in the town now.
Good luck with the project, I will come tease you from dynmap!
