My scenario is making the assumption that all 3 cuts can fit in the long siding, all 3 cuts used a helper cut in ahead of the caboose, that the road engine always took the load down to Antonitto and the helper always went light engine.
1) the first cut is left at the East end of the long siding,
2) the second cut is left at the middle of the long siding and the road engine is released via the cross over.
3) the helper pushes the second cut up to and couples to the first cut.
3) the third cut pulls up short of the first switch, and the road cuts of and goes down onto the mainline and stops.
4) the helper pushes the third cut over the hump and couples to the train.
5) the road engine runs back West then East and couples to the caboose and pulls that back West to release the helper.
6) the helper reverses back, clears the switch then moves on East to Antonitto.
7) the road engine couples the caboose back onto its train then reverses to clear the first switch then goes down to the front of the train.
I am assuming the third cut will be smaller and the helper can push it over the hump, the helper may even hang around then couples to the rear of the train to help the road engine build up air then departs for Antonitto.
That's how I would do it on my model railway!
