I have a postwar Lionel 2243 single-motor F-3. I was wondering if I was to buy a 2243C "B" unit and try to pull three or four postwar aluminum passenger cars would the F-3 be able to handle that load? Even if it could pull that load would it be bad for the motor? The reason I ask is that I believe these single motor 2243 F-3 A-B's were only included in freight sets, not passenger sets with aluminum cars (those always had the double-motor F-3).
The single motor Texas Special F-3 was sold with the smaller, plastic streamline passenger cars, which got me wondering if the single-motor F-3 could handle pulling the aluminum passenger cars or not.
