Thanks to the efforts of a couple of members here, I now have four nice groupings of classic ConCor PAs.
It all started with the arrival of three dummies from
@chessie system fan , a beautifully custom painted A/B set of L&N, and a Southern A unit.


Next, i got a great deal on a fully powered ABA set from
@ai5629 Jeff Lopez , all three drives are silky smooth runners (compared to their contemporaries anyway) Now, for those of you old enough to remember, three powered PA drives can pound out a 200 car train on an N track layout without blinking an eye, so I set about the task of shuffling things around a bit.

First, I picked up a bargain bin deal on a Dummy A unit while I was in San Diego last week.

This gave me some parts I would need to complete the transplants. (The Southern and L&N engine came with the pilots fixed to the shell, and I was not able to salvage the one from the SOU cab) also these were set up with a home brew link and pin set up, presumably to get closer coupling distance.
To keep the L&N shell intact, I opted to power the B unit. I replaced the link and pin set up with Unimates to keep the coupling close, and put a Rapido in the back to interface with my old passenger fleet. Since ConCor provides a light rig in the dummy A, the B can push it around and no one is any the wiser.
The other A drive went under the Southern shell pretty seamlessly (once I had broken off the OEM pilot)
With a bit of repair and replace on the dummies frames, I was able to put the B&O set back on the road with a powered A and two trailers. The set looks great handling my 8 car streamlined Columbian.
These, of course, now share the spotlight with my original PRR ABA set, also a singled powered A and two trailers.

When I run all four, the lights in half the county dim, but there's nothing like the thrum of those old motors as they whisk passengers along to their holiday destinations!
