The LSWR D15 class 4-4-0 was the last steam locomotive design by Dugald Drummond for the London and South Western Railway in 1912. By 1912, Dugald Drummond had built several classes of unsuccessful 4-6-0 express passenger locomotives. The result of these failures was that when he designed what was to be his last class in 1911, a new 4-4-0 design emerged from Eastleigh Works in February 1912, with what was to be the first of his D15 class. Contrary to Drummond's previous 4-6-0 designs, the D15s performed exceptionally well and were put to work on trains to Bournemouth, where many drivers noted their superior operational characteristics when compared to the T14 class 4-6-0s. This was due to a marked reduction in coal, water and oil consumption, and easier maintenance. These successful locomotives worked, in the main, out of Waterloo and prior to electrification had a virtual monopoly of the Portsmouth expresses. All 10 worked into BR ownership and were eventually retired by the end of 1956. None were preserved. |
