> Mines do this for equipment that operates a fixed track
Ok, ignore mines (though I don’t think this statement is universally true), you can find the same examples in forestry where equipment out in the bush runs on electric batteries being charged by small onboard ICE engines, and the logging trucks themselves are switching to this as well. None are on tracks.
Onboard ICE sounds more like diesel electric than fully electric. The addition of some batteries for efficiency and peak power availability doesn’t change things all much I would still call that diesel electric.
