Yes, lots of trains. I used all trains to supply fields and factories instead of truck convoys.

As for the trees, I did have custom clutter tiles made to give it a more winter feel, but ran into an issue where an occasional tree would pop up in the middle of a train track. To fix it means totally redoing the clutter tiles. I just ran outta time before the terrain was needed, so I used default clutter for now. The new clutter will be in place by the next time we use the terrain in the AvA.
