EREV is different from diesel-electric in that the EREV has a large battery whereas the diesel-electric locomotive does not. But the "ICE engine drives a generator which drives a motor" philosophy is similar in spirit.
Yes true; good point. I think this is changing (e.g. regen braking for aux. power on passenger trains maybe eventually capacitors for traction drives in the future), but currently and ~almost all the time, this is correct and a good point.
