1. Just Recently i saw that you can upgrade your tracks to electric tracks at no cost. Just put one electric track next to existing one, end extend it by only one track. It will cost you 0. 2. Building tracks is less expensive when you build it by one. Just build one track, leave space, next track, leave space and so on. Looks like this: - - - - - Then you connect the holes, but also by one: -------- It's a cheap way to build long connections. OFC you sometimes must build longer tracks, to avoid high grade. But on the plains it's very cheap. The same applies to expanding from one to two tracks - expand it by one, then connect the holes. Hope you enjoy it ;)
