I guess everyone is now convinced that EMD E-series passenger locomotives contain two diesel-electric power plants, each of which provides electric current to both traction motors of one truck only? Good. Then, let's look at how this worked in pre-Amtrak passenger service.
Most mainline passenger trains pulled by E-units had two -- sometimes three -- units. Union Pacific used up to six units, and SP and Burlington used up to four, at the end of their respective passenger service, because they combined trains on some routes. but two or three was normal elsewhere...
