Shielding 750 volt 3rd rail ?
ISTR that the ultra fast maglevs and hover-guideway thingies running at
400km/h, and indeed over 500km/h use conductor rails to supply the juice. Check if there's any overhead on the Chinese maglev. I'd suggest that we'd be in strife somewhere above 600km/h for side contact or bottom contact conductor rail supply - much higher than for catenary strung overhead contact wire.
