Excellent Video!
Of course, it also make a clear case for completely upending the entire rail industry in order to resolve such nonsensical dis-efficiency.
The moment the track is nationalized or otherwise becomes full-common carrier, you radically cut the complexity of such operations and the number of moves required.
This, of course, is how highways operate; imagine if trucks could only operate alone roads/highways owned by their trucking company? That sound absurd on its face; but then it can be no less absurd in rail.
Rail companies should own the cars, and manage the staff/logistics that operate them, but not the actual rail. A curiosity that it hasn't unfolded that way, since it would actually benefit the bottom line enormously.
Once the track is common carrier, it means that movements between different tracks can be optimized, including yard storage.
This would also improve competition and, in theory lower costs.
As an interim matter, I would argue for legislating universal running rights and a fixed fee so that trains can begin using anyone's tracks; existing runs get grandfathered preferential slots; but after that, first come, first serve.
Now, bear with me, I'm going to be marginally fanciful here, but this is not meant to be absurd over-reach, merely looking ahead a bit to where I think last movement should be....
I don't understand why end customers don't have limited push-pull power on-site, the idea of having a mainline loco do on-property maneuvering seems needlessly painful.
For clarity, I'm not suggesting that on-site power needs to be an industry owned loco, there are lots of ways to shift cars around, you can use any number of forms of winch system (think pulling a roller coaster up hill); you can do this from under a train, alongside a train or overhead. You simply need the power, and a place to attach it to the lead car. Train car breaks should really have blue-tooth at this point.
Alternatively, one can obviously use much smaller powered vehicles (vs mainline locos) for small movements.
Also, looking at the runarounds has me wondering why turntables aren't more common. Seems like it was a very practical idea.
