Both the entrance ramp and the platform are actually entirely in

open air, and it is therefore emphatically not 'illegal' to smoke
there.

You are mistaken. Railway Byelaw 3 makes it illegal to smoke on any
part of the railway where there is a notice indicating that smoking
is not allowed. There is no reason to believe these notices can only
be placed in enclosed spaces.

Interestingly, violation of this byelaw is an offence with a penalty
of a fine of up to £1,000, while smoking in violation of the
Smoke-free Regulations can result in only a fine up to £200.

Ah, IANAL, as you can probably tell - And thanks for this and all the
other replies.

Its just that in the past a simple 'no smoking' or
'burning-fag-with-red-slash' pictogram seems to have proved sufficient
deterrent on trains etc, even though lighting up was illegal under the
Byelaw. Now that NR stations put up the same 'statutory'-type signs
that pubs, shops, etc have to display, it does tend to imply that they
want people to believe that the blanket ban at stations is a result of
the new law.
