All I had was a pocket watch and clipboard. You need to know the route pretty well. You got that fancy black map to look at too. There's no car numbers listed, just the number of cars in the cut. You can put'em where you want'em. Its Free Roam so do it how you think best. Theres 18 orders above, you guys tell me if it makes sense to you. As well, if you have all the add-on stuff, the yards are all full of low poly cars, so you need to look at the map, read you orders, check your switches and go.
Here's a few pics
Order #4 completed. Them are Jessie's repaints, fine looking cars !!

Hog Island Yard, the tanks and the string of boxes on the far right are yourn.

Possum's ragged old chip cars, your switcher is parked just foward of'em ,Jessie's cars as well.
