These large 0-6-2Ts were built by Kitsons in 1908, and, according to RCTS, with the obvious exception of tanks and bunker, were virtually identical to Taff Vale O4s. Its not immediately obvious to me why this should be, as the O4s were never built by Kitsons. I shall be interested when I get to the Taff Vale classes. The obvious feature of the class of 3, in common with some other Cardiff classes, was the long tanks, heavily sloped at the front. I can't make my mind up whether I like this or not aesthetically! Anyway this is the sole GWR reboilering of the 33 class, which lasted until 1953. One of its sisters was withdrawn in 1930 and cut up in 1934 after failing to find a buyer, and the other, withdrawn in 1934, was soon sold into industry, and survived into 1960, just a few years too early to have a chance of preservation.
