Adam,
Yes! On the G&SWR Robert Whitelegg wreaked havoc with many of his predecessors locomotives and turned them from competent machines, for the task they were built to do, into basket cases. To be fair to the man he inherited a very run down collection of engines, primarily because of the ravages of the Great War, but also inadequate facilities at Kilmarnock works. His plan to standardise boilers was a good one but alas his designs were rather poor and not as good as those replaced. That plus tinkering with the valve gear, which resulted in very poor valve events, sealed their fate with the result that virtually all had gone within 10 years of grouping. Having said that his rebuilt engines did look good and gave the crew a much better cab to work in.
His Baltic tanks were a triumph in publicity terms but not in service with innumerable mechanical problems. Their route availability was seriously restricted, as is my model, and we’re not liked very much by the crews. Their best feature being the provision of coal watering sprinklers in the bunker! That the usually very canny board sanctioned their building, over £16k in 1922, has never really been explained. The LMS kept them going until new boilers were needed but that wasn’t very long.
However the Baltic pug is synonymous with the Sou’West and I had to have one in my collection along with many of its predecessors. I do also have an example of his earlier LT&SR pug.
Ian.
