Railway bridges

I took another photo to show that the railway bridge looks a little bland beside the extension bridge

Yes that would be nice but the actual bridge design is a bit blah, should have been like the golden bridge.

I'm hoping there'll be more in each of the weekly challenges

You need to put the bridges over water for them to work correctly. I need another dozen or so. 

I love the addition of railway bridges, but I am unable to lay tracks over them. Every time I try, the tracks want to route around the bridges and go over the adjacent roads.
