I don't know.
The crew seems more concerned with the front of the locomotive and the drivers.
An observation at the 12:19 thru 12:30, looks like the second driver has something coming out of a line right in front where the wheel meets the rail. I think this is a flange oiler (just guessing).
Best I can tell, all drivers have flanges ( I was thinking there may have been some blind drivers in the middle).
All the wheels on the tender appear to have flanges.

Not sure what you saw there, but some of those drivers seemed to be just barely on the rail.
