It's part of Lionel set 36188 and I may be wrong but believe lionel number the engines 36189, 36190, & 36191 ( powered A, non-powered B, and non-powered A ) as that's how I have them cataloged in my inventory.
The 6 should be an 8: 38188, 38189, 38190, 38191.
Not familiar with those particular units Bill, but considering the numbers are 'similar' most likely it would be a straightforward swap. Both should have black trucks as well.
Thanks what I was thinking but wasn't sure.
Thinking that would make the Southern set a good puller. I have two of the 24519 B&O B-units now with tmcc and dual motors.
The 38190 and 24519 are completely different animals. They don't share any components, and the shells are not swappable.
