Hi there,
Sorry if the question has already been asked, but I couldn't find the answer through the search engine.
I've been wondering how you build railroads, as the manual says you can.
All the units that I have in what I suppose is a good position to lay down tracks (i.e. with rail in the adjacent province) have the button greyed out.
Could anyone let me know if there is a way to do so or if the button is simply for rebuilding as it reads on the tip ingame?
Do you need an engineer or something?
Thanks in advance.
