OK fair point. You and I may have a more holistic view of the whole
complex ecosystem of components that are needed to make an electric
train move, but I can imagine the "general public" may well have a
narrower view and see the pantograph or contact shoe as the "power
supply to the train". 

When tagging hyperloop and maglev systems there is often no *contact
system* as such I guess we should think of something like
"electrified=induction"?
