@MELGAR posted:I have never noticed any temperature rise when running my modern O gauge locomotives. Who needs to run for eight hours continuously? And I doubt there would be any temperature effect even then. In particular, I have two MTH Premier PRR G-5s locos (PS-1 and PS-2) that have been running trouble-free for more than twenty years. I don't think that design could be considered inadequate. As for the 4-6-6T - we shall see.

@MELGAR,...Who needs to run for eight hours continuously?
I do...I didn’t get into this hobby to admire them....my junk goes to work!..😛😛😛....but that’s just me MELGAR, for most of you guys, they’ll be fine forever....and yes, I agree with you 100%...that little tank engine will be happy pulling 2-3 cars for a couple hour spurts for eternity.......but don’t get me wrong, if I get one and it don’t do what I want it to do, I’ll gut it like a fish and start over....🤪
