Railway bridges

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.

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

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

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

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