Why and how would the Class 92 locomotives have to be "configured
for HS1"? They do support TVM and KVB, don't they?

I think they only have it configured for the Channel Tunnel, which uses
different speed bands from HS1 or LGV. ISTR that when one freight train was
allowed to use the CTRL it had to do so under special regulations as it was
effectively unsignalled.
