Nothing strange about the requirements of GO 95, which applies to the HSR.

in the tunnels

Everywhere else.

While 23 feet is GO 95's preferred height, it can be a minimum of 21 feet, and the San Diego trolleys work just fine with 21 foot wire. Possibly the SDMTS feels 21 feet precludes double stacks. There can be variances (lower wire) under certain conditions for existing bridges over the track.

Only as long as those possibilities are in compliance with GO 95. I expect some sort of waiver has been issued for the wire in the tunnels, and it precludes operating freight cars through them which are taller than certain height.
