Exactly there is space for it. The trains would run smoothly too instead of stopping and everything else including the car traffic stopping lol.
I actually thought were finally gonna get train bridges in this new season update but it did not. I saw a youtube video about it with the new buildings.
I like however that they increased the points in the event track rewards. It was ridiculously hard before.
I think the developers are forgetting its SimCityBUILDIT so they should focus on the designing and building a beautiful city aspect of the game more cause thats what we came for not freaking wars haha.
