@KRM posted:it is my understanding a Lionel E-unit can run 4 pulmore motors. I see it everyday with my 4 motor A-B- A ALCO unit. But it is a bit much for the transformer. I think the better option is three motors.
Not sure where @KRM came up with his knowledge, but this is just something I've been aware of for 45-50 years... maybe from Frank Kanzler or Earl Gardner?
