I read with interest Howard Smith’s article ‘How to model an abandoned wagon’ (May BRM), and your reference to the inspiration photographs on Flickr, by Brian Creasey, of two abandoned wagons dumped beside the up line, next to Beckenham Place Park, between Ravensbourne and Beckenham Hill stations on the Catford loop line in London.
I'm quite familiar with the location, and that both wagons are ‘Flatrols’, which were derailed during an engineering possession and dumped beside the line. One wagon can be seen from passing trains, the other not so easily, as it is upside down and buried in ballast and vegetation growth.
For many years, I tried to find the identity of the upright wagon, and had been in touch with Paul Bartlett. In January 2017, Brian put forward identities for both wagons, but was not sure which was which: BR diagram 2/530 ‘Flatrol’ EAC DB900110, one of 20 wagons B900109 – B900128 to Lot
3252 built at Shildon Works in 1959 and BR diagram 2/512 ‘Flatrol’ MVV DB900024, one of four wagons B900023 – B900026 to Lot 2641 built at Derby Works in 1955.
