Connie has since had several runs just north of 70 min at scale 12-13mph with little, if any, human intervention once she gets going. 80 to 90*F. Same fuel etc. as before. Definitely getting better with age.
Hallie, a RH Bertie, had a 50 minute run for the first time yesterday. Constant, slower speed control is a little more difficult with this one. I'll be fitting her for R/C over the next few days. Just waiting for a delivery from RCS. I'll start with a tender-based system to see how everything works and then (perhaps) try to install everything on board the loco.

One contributor to consistent, low-speed runs has been the use of very short wheelbase rolling stock, including modified Hartland gondolas and Bole Laser Craft wagons. There is far less drag around the corners than with full-size coaches.
