The extra crossover allowed you to go in/out at times without having to go all the way around the ovals. However, on a smallish layout, sometimes having to go further adds to the operational enjoyment.
I thought about it and added a passing siding back in, just a little shorter and in a new location, so see what you think.
I don't have any experience with scaling down a large industry so it looks "right" in a small space and still gives that sense of "size". I'm sure there are some members here though who can point you in the right direction.
