I had wondered what these NR Validators were, but I now see that
validators have been installed along platform 8 at Paddington (also
covering platform 9). There don't seem to be any for platforms 1 to
5.

P1-5 are dedicated to services that do not stop within the zones, the lack
of validators will help get that point across.
