Railways, Railways, Everywhere!

To fit in with the victorian steampunk feel, I'm going to add a LOT of railways throughout my city. I want these on multiple levels going from ground level all the way to the top of buildings. If I can get the lighting working correctly I think it'll add a nice shadow effect on the player below (even at night time there's lights from fires etc)

This is what I've got so far, I still need to make corners and tracks for ground levels.
