Interesting video and very nice factory model paint job on this one Jon
(opinion) they were a really a bargain when introduced (if you made the initial reservation)
sturdy and run-able out of the box and looked great!
They still get a lot of love on E Bay too, though I prefer the CSS&SB 800 version as it outlasted the Milw's by 8 plus years.
As an aside I landed a factory Weaver RS11 with that Lionel control system, wanting to have at least one
control/sound equipped unit to run my auto parts train with on the modular club's pike where DCC in all "flavors" is more or less the practical standard anymore as opposed to analog. But I could not get around that EMD 567 sound subbing for the nominal 12 cyl 251 on units, and (the real killer) the factory TMC was more than a tad cranky, aka resetting on switches other engines had no issue with. 8^(
