@RailRide posted:Just out of curiosity, are these sort of upgrades feasible on K-Line's scale Hudson and Berkshire? I hear their motors are sort-of underpowered and prone to conking out under heavy loads. I have one of each (bought new when they first came out), and while I haven't even gotten around to running them, it's something to keep in mind for the future.
(but in the meantime, if they ever get their turn on the "test-track" in stock form, I'll configure lightweight, easy-rolling trains for them since I already have stump-pullers that can handle as many cars as the loop will allow).

I've done the swap on a K-Line Berkshire: K-Line/Lionel/MTH Berkshire hybrid | O Gauge Railroading On Line Forum (ogaugerr.com)
You need the entire chassis from the Lionel Legacy version from 7-8 years ago. Literally everything else from the K-line chassis bolts onto the Lionel chassis (rods, valve hanger, cylinders, pilot, trucks, etc) so you just need the chassis and worm shaft from Lionel. There is no provision for the puffer smoke unit from K-Line in the Lionel chassis, so switching to fan smoke is required. Pete @Norton was the first to notice the similarities between the chassis. Pat @harmonyards was able to set up a 9433 Pittman to fit the chassis. It's an involved swap but mostly bolt in.
