The old Mantua (good stuff) in the early '60's used self-contsined power trucks, and F units had the room for two powered trucks. I did up a couple this way, and wired them in series (I think - it's been a long time ago) and never had a problem. My A-B-A set of Mantua Santa Fe F-7's could pull paint off a wall!
They were a little fast, but completely controllable with proper throttle artistry. Many feel that multiple motors must be perfectly matched for proper operation. Not so! Unless the incompatibility is completely off the wall, they will equalize under a load and all pull together. After all, even the real ones use multiple motor set-ups.
