G&SWR 128 Class

The Glasgow and South Western Railway 128 class was a class of two 4-6-0 steam locomotives designed by James Manson as a development of his 381 Class 4-6-0s, and were his final locomotive design before he retired. The North British Locomotive Company built them in 1911 at its Queens Park works, and they were considered both good looking and excellent performers. They were numbered 128 and 129 at first, became 512 and 513 in the G&SWR renumbering of 1919, and after the 1923 grouping became London, Midland and Scottish Railway numbers 14673 and 14674, before being scrapped in 1933 and 1934 under the LMS drive for standardisation. With the 381 class they were the only G&SWR locomotives to use the 4-6-0 wheel arrangement and to have Belpaire fireboxes. No. 129 was built with a Weir feedwater heater on the boiler, removed in 1919, and for a period ran as a 4-4-2 after it broke a trailing rod.
