I'll try to sum it up for everyone...
The mainline has no freight yard, just a coach yard. The two stubs in the upper left are station tracks. The hidden helix connects the upper level to the lower level which has a continuous loop and a reversing loop with a passing siding.
We will make up small passenger trains with a switcher, then bring out the road power and place on the point. We will run down, then run continuous loops to travel "mileage" until we are ready to "head for home" via the reversing loop. Once arrived back up top we will cut the road engine, service it, and turn it on the turntable to be ready for the next run. Running 2 passenger trains at once should be a challenge for 2 operators. We can also bring in passenger trains from a virtual station somewhere down the line via staging. Might be fun to bring one in, setup a meet at the siding, reverse direction and take it back to it's virtual station in staging - all while someone is running freight on the branch.
Since we have no room for a freight yard all freight ops will be done like a Terminal RR - Moving cars between industries, interchanges, and staging. The freight engine will come down from the engine facility in a light move, do its work, then return light.
As I mentioned, this is a virtual copy of John Armstrong's design, so I'm not messing much with the Master's plan.
I attached the Anyrail file, but just be aware that I don't have all the elevations done yet so it only works in the 2D view not 3D.
