Greg,
If you want a usable yard that you can break down/make up trains I made a few modifications plus kept the yard lead. If you already know how a yard like this works, ignore the rest of the post.
Basically, an arrival train coming down from the top would back into the arrival/departure track and stop with the caboose about half way down it. A switcher parked at the end of the track would grab the caboose and using the runaround track move the caboose out of the way The road engine would then push the cars all the way to the end. The road engine would then uncouple and move to the roundhouse.
An arrival train coming from the bottom would go right into the arr/dep track and the road engine would stop about half way down. The road engine would then uncouple, go to the end, back up through the crossover and using the runaround track go to the roundhouse. A switcher that was pre-positioned on the yard lead would push the cars all the way in.
A switcher would then take the cars from the arr/dep track and move them to one of the classification tracks.
Do the reverse for a departing train.
Beyond the crossover you have a short section of track for your cabooses.
Gives you something to do while your other trains are running on the main lines.
