I have quite a bit of info on wiring two E-unit controlled Lionel diesel locos together, plus, modifying a single motor unit to 2 motors. There are electronic modules designed for 2 motors available, but am sticking with the mechanical. The E unit contact rating as to total amps has eluded me, but I just found this from 2001,
"Lionel rated their e-units (mechanical units) for four motors; so you are not limited to single-motor locomotives nor to two locomotive units, as long as the total number of motors wired together is no more than four."
Is this a true statement?
