This looks ok to me.
A situation like this occurs only once in Germany (Birkenwerder station), currently, only the electrification by rail is mapped there. A tagging similar to your proposal is already in use for tracks, where the overhead line can be switched between different systems (15 kV 16,7 Hz AC <-> 3 kV at Aachen Hbf and 15 kV 16,7 Hz <-> 1,5 kV DC at Bad Bentheim). As both cases are very rare, it should be ok, to use the same tagging for both? Micha
