This is a early version sketch of a Barry H class. There are some puzzles. Photos appear to show a much narrower dome than the various weight diagrams, Barry and GW, which I've tried to reproduce. More problems come from the underframe being in shadows on most photographs. No brakes shoes on the leading driving wheel, and although I've drawn them the same, I have a suspicion the brake gear on the second pair of drivers was different to the other two. Finally the best profile shot of the L/H side of a locomotive I found shows a very prominent injector (I think) with a large diameter pipe leading a few inches below the footplate to a box like structure between the 1st and 2nd driving wheels, but I can't make any sign of it out in the shadows in any other photos I've found. No sign of it in drawings in Mountford and Russell. I try to avoid drawing injectors unless I have a very good reference as they are such a pain to get looking vaguely right, but if the universal fitment was as per this locomotive then I shall have to make the attempt. However I note that RCTS states that the locomotives started life with an exhaust steam injector which was fairly soon removed, so I wonder if its that early fitment that I am looking at. Anyone know?
