Hey thanks very much for the suggestions, glad you're enjoying the game.
Lots of stuff others have also asked for so it's likely I'll be adding a lot of what you want. You can check out the Steam forum to see what others suggested.
Try a night time environment, the radio tower and light house actually do have animations, I should add them to day time too though. I agree lots more animations would make it look more alive.
Roads would be nice, I am planning to let you build them the same way as tracks so it is all automatic.
