I like the revised curve leading out of town.
@Mark Boyce posted:.. I may just have a lane cross the tracks from the aisle (to the farm) and not connect to anything (else).
I think a driveway crossing the tracks to the farm from the aisle is a good compromise if you want the space a through road would have taken away from the farm acreage.
Here's another idea. With the revised curved exit road idea on the table, this raises the question of the notion of also having a road going into a tunnel, which is cool IMO. If you like this idea, maybe a second road could be added coming from the walk aisle, crossing the two lower level tracks and then heading into a tunnel somewhere around where you had it earlier or maybe a bit to the right of where it's depicted in this borrowed image (is it ok to borrow your picture for illustrating the idea?) :
