I helped Bob on the NERW and we agreed to a max number of objects on a tile. We wanted to keep the route playable by as many people as possible. From what I can tell my town is the hardest hitting. When coming into my town from the west, on your left the terrain slopes down with a village in a valley with trees visible on the other side of the valley at least 1\3 of a mile away. To your right you are looking over a couple of yard tracks and sidings, at least a 1\4 mile in cab to the farthest siding. Now picture you are on the farthest siding, you still want to see at least 1\3 of a mile away from there. That basically loaded up that tile with just the cab view and some on the tiles on either side.
Don't really hear people complaining about frame rates.
