LBSCR Works 'wet plate' neg by Barnwell of Brighton Works stated to be in 1879. This shows a Coke wagon that I now believe to have vertically slatted wooden sides rather than corrugated iron. At least one coal wagon is from Boothe Brothers of Eastwood.
The horseboxes are Nos 7, 30 and 38(or 36?) and the open carriage trucks in front of them Nos 32 and 43.

I would love someone to confirm the date based on the background houses
