There are different ways to achieve the shunting required here, but my favourite version goes something like this...
1. Uncouple the tankers from the coal wagons and park them on the siding two across from the coal wagons.
2. Pull half of the coal wagons through the loader and stop/ uncouple when you need to keep your run-around switch clear.
3. Go to the other end of the coal wagons and push the remainder through until the load complete message appears.
4. Pull the coal wagons back a little to clear the far switches and then uncouple the caboose.
5. Back up to clear the points so you can push the caboose back past both consists on one of the vacant sidings to park it near the line terminus.
6. Go to the rear of the tankers, pull them back clear of the siding switch and then push them through the diesel drop-off. (Unloading can be achieved with just two stops.)
7. Draw the tank cars back onto the adjacent siding and then push them up to couple up to the caboose you parked right up at the end of the line earlier. (Make sure they are clear of the points.)
8. Run back to the other end of your coal hoppers and push them up towards the tankers to couple up gently before departure to the yard where you'll drop off the tankers and caboose...
Should be able to complete all of this within 30 minutes and before the top of the hour.
That's just ONE way to get the job done (and not necessarily the most efficient.)
Have fun with this one. I find that it is one of the most satisfying (and in earlier beta editions that were very buggy, most frustrating!) sessions to complete in Kickstarter County.
