Agreed with topic starter. Game is catching, but need some improvements:
I think it would be nice to see:
1) Train station sticking to rails (or even place station over existing rails, if they are straight).
2) Possibility to upgrade old rails to highspeed one, to upgrade roads that cross rails.
3) Maybe as advanced option to choose wich way will go train. Its hard to controll trains if there are many parallel rails and they have crossing.
