This is a switching layout.  Trains consist of 1 or 2 locos and 5 - 7 cars (passing sidings are short).   Beside the siding length others factors of the number of cars per train are the number of axels of the locomotives along with the physical weight of the model loco and the tight curves.

Operating as an out and back (primary operating type) SEE A workday on the GD&R

Turn 3 will take the right leg leaving the yard. At GR Junction within the BID the train will take the left leg (see image below). After making 2 complete loops it will service customer 4 and then head on to customer 11. After using the passing siding (located at customes 6-8 on track plan) and running the loco around the train, Turn 3 will work customer 9 The train will head back towards the yard, working customer 10.
