Promising photo. The two bridges are interesting here. To highlight both, you might try a different perspective, perhaps closer to get a good view of both bridges. The sky does nothing to help this image: try either waiting for more interesting light or crop most of it out.
Really like the colours that you've been able to capture with the engine and the train and also the automobile. The various colours of the bridge and brickwork are great also, along with the tree line, grass, etc. Nice job.
I think there is a little too much vying for my attention here, particularly in the foreground. I don't know how it could be improved upon, but perhaps if a telephoto lens was used to get nearer to the subject. An interesting scene though.
