This is a few pictures from the updated version of my map.
A barge has been added so that both sides of the bridge now has one (1 for either team).
The bridge has been updated with some new supports so its more realistic and the train has been moved because, frankly, it looked pretty ridiculous where it was. You'd never get a sideways train with the bridge intact. Anyways, it now also provides a sneaky way across the broken bridge so thats a bonus.
I have also extended the railway track on either side of the bridge because it suddenly occured to me "how on earth is there a crashed train on this bridge? there's not even any tracks leading to it." so I fixed it up. I added a small train station on one side of the bridge and both sides now have track that runs off outside the map to give it an authentic feel.
Finally I made a couple of quick changes to make the map more believable. I lowered the rocks either side of the map so it actually seemed like a river. If it was just a lake you wouldn't build a bridge over it, you'd just go round it, especially at that size. I also added a faction glider at either side. It doesn't really provide much of a bonus as you'll likely get shot down, but if you're mic'ed up, you can give out positions to friendly units.
Anyway I'll add more updates as people bring stuff up that would make good additions.
