A scaffold caught without guard rails or a protective barrier at Paddington station
Credit where it's due - there's a decent hill-slope brake in place, but is the absence of a guard rail at the top of this scaffold deliberate? The painter is certainly going to have to jump if it gets knocked by a car - and given the (shall we say 'cavalier'?) nature of some London drivers, plus a lack of any protection around the structure, this is a distinct possibility.
Many thanks to Cecile Searle of London for sending this in.
