It was thus not possible to run them as diesel/electric as the motors cannot be a generator and motor at the same time.
Confused?

That is correct. Therefore, one engine to generate electricity for the storage batteries and the other engine turning the electric motor turning the single screw. Ok, now we are both confused. :rotfl:The diagram above from the link explains it very well. It is explained the same for diesel/electric locomotives. ...just on dry land!
