Another Heathrow landmark will soon be no more, as after 15 years since R23 became defunct, the famous old gasholder at Southall with 'LH' on it in big letters on the approach to R23 is finally being demolished, as the last part of the old Southall Gas Works left.
Demolition started a few weeks ago, and as of this morning the top third or so is now gone, with only the bottom half of the 'LH' now visible.
