Butch, the story of your experiences is precisely why "operations" groups have the reputation they do. You might not believe it at first, but folks who used to work for the railroad are often the ones to walk away first, simply because we don't want to leave feeling wrung out like we did a day's work as a hobby.
Our ops group here purposely tries to find the balance that makes an enjoyable afternoon's operations. We work to switchlists and trainorders but the idea is to emulate rather than replicate. The "schedule" is a linear progression of tasks rather than a schedule with clocks, the operators set their own pace.
There is no attempt to make things complicated, no puzzles to solve, artificial pressure. To be honest, emulating railroad ops arguably includes the idea that the industry goes to great lengths to make things work smoothly and efficiently, not solve purpose-designed "timesavers" and switching puzzles.
No jargon, no adherence to artificial replications like waiting some number of minutes to "pump the brakes", no car cards, fake bad-order events, none of that. Run the scenario, switch the cars as needed to the wheel report and switchlist, throttle in one hand, donut in the other, talk about what you've been building, get as far as we get and go out for supper.
I think we have the right balance, as no-one has quit either from boredom on the one hand or from not having had a relaxing enjoyable day on the other, not in the five years we've been doing this. There are a fair number of guys who worked for the railroad mingled with model builders, gamers, HO, N, live-steamers, quite the mix and none of what we're poking fun at with that cartoon, probably because most of us have been there and don't need to go there again.

I'd like to think we are pushing the envelope of proto-ops simply by backing off the artificial pressure a bit.
