Wow... gotta ask, Bill - are all of those F’s powered??? Looks like an ABAB-something!!! And what were you pulling that required that much power???
Not all powered, the ABABA F units are from Lionel many years ago. 2 powered A's, 2 B's with sound, and 1 unpowered A.
Thanks Bill. That is a very impressive (and, I assume, noisy) “lash up”!!!
