Independent PTC. UP has published some pictures and discussed some aspects of the system.
2816 has independent PTC, something their steam crew is very proud of. So proud that they don't want to discuss any technical details at all, and keep it 'proprietary' (one member of the crew said that since they put 2 and a half years of work into it, they're not just giving the 'secrets' away.)
U understand 2926 is to have independent PTC (not dependent on a link to equipment in a diesel or support car) and would appreciate seeing whatever approach they have implemented.
What this calls for, in my not-so-humble opinion, is a Firecrown-supported technical article in the new Trains, going into detail about what is required to implement 'correct' PTC on a steam locomotive and how the different railroads that are doing it met the challenges.
And for old time's sake, here is pre-PTC Challenger 3985 including some rare mileage at track speed on that mighty good road to St. Paul, MN in 2008.

Here is a 15-inch gauge 4-12-2 "almost" Union Pacific type that is under construction at Merrick Locomotive Works in WI.
First one is a running gear test.
Second one is near completion.
You will note left-side-mounted air pumps, two cylinders and rectangular tender with six-wheeled-trucks as differences to the 9000s.

Here is an all-color snippet of UP steam on the Kansas Division in the 1950s including a 9000 Union Pacific, several 3800 Challengers, FEF Northerns, a 7000 Mountain and a 3200 Pacific really making time.

Thanks, kgbw49. I don't think I had ever heard a three-cylinder locomotive running before. Weird.
