L = locomotive, starts at D
G = goods, starts at B
Co = container, starts at C

1) Move L back toward the viewer.
2) Drive L forward (left at bottom switch) and hook to G.
3) Bring G-L back to the viewer again to pass the bottom switch.
4) Drive G-L forward (right at bottom switch) and leave G somewhere along rail D.
5) While on rail D, push Co into the bumper slot A.
6) Drive L (nakedly) through C, onto D, and then reverse to drive toward the viewer, switching appropriately.
7) With L on the viewer's rail, drive forward and hook to Co.
8) Move Co-L backward toward the viewer.
9) Move Co-L forward, taking a right through the bottom switch, and colliding Co with G.
*) At this stage, rail D should have the configuration L-Co-G.
10) Pull everything back toward the viewer.
*) Now, the viewer's rail should have the configuration L-Co-G (bottom to top).
11) Push the train upward, taking a left at the bottom switch.
12) Going all the way up/left, we now have G parked in bumper slot A, and Co parked at B (never to move again).
13) Unhook all cars from one another, and drive L back to the viewer.
14) Drive L forward and take a right at the first switch. This puts L on rail D.
15) Back up past C to hook to G, and drag G forward a little to park it.
16) Unhook from G and we're done. L can move freely along D and the incoming arc.

That was a bunch of steps but if you count carefully or do this out on paper there are nine switch moments.
