Sorry. But the first TGV line (Paris Lyons), each locomotive was equipped with
2 pantographs and power systems. One for the high speed lines, and the other
for the traditional lines. And during the switch-over from one to the other,
it was evident inside the train because there was a period where there was
only minimal power (no air conditioning etc, just lights).

Also, the Eurostar is also equipped with dual power systems because the
british railways between Folkestone and London provide power on different
voltage (as well as providing it on a third rail instead of overhead wires.
