Oh. Figured it out. You have to click on a square next to a railstation and hold the mouse button down for 2 seconds on that field to make the build menu appear.
What a very, very unintuitive and annoying control scheme. Just do leftclick to build, rightclick to move camera around instead of this hold-for-2-seconds.
Yep, this is not the final control and also not the final game, just a prototype. The building of rails will be changed as the rails popup will be disabled and you will see the possible routes instantly as you build one. You click on the desired one, and you will se the next ones in that moment, etc... So you have to hold down only once and then just click/tapping on the right ones.
Amm... yeah I'ts maybe sounds a bit too complex, but belive me, it will be cool!
Also there will be tons of improvments and quality of life updates. This version was about to make it work, now comes the fun part of the development :)
