Plarail Round-Trip EF66 automatic shunting yard (video)

Haven't heard from DuckGWR in a while. I'd completely forgotten these forward/reverse locos and track pieces were a thing. This other channel I found named #MYPLARAIL (myplarail313) made three videos showing this feature being used for un/loading with tipping hoppers and coming back without using an oval, turntable or loop; essentially what a Big Loader set does. They even showed how to make a custom direction trigger for others who have these locos. I feel this is a more interesting use that actually warrants abrupt direction changes. You once showed a video of something similar here with servos controlling stop/gos and a three way turnout to sort cars into each track, though it wasn't "purist" unlike this project. Thanks for sharing.
