The locomotives of the Glasgow and South Western Railway (G&SWR). The G&SWR had its headquarters in Glasgow with its main locomotive works in Kilmarnock.
The G&SWR was formed in 1850 from a merger of the Glasgow, Paisley, Kilmarnock and Ayr Railway (GPK&AR) and the Glasgow, Dumfries and Carlisle Railway (GD&CR). A number of other companies were absorbed by the G&SWR or its predecessors, including the Ardrossan Railway, the Paisley and Renfrew Railway and the Kilmarnock and Troon Railway.
One notable feature of the G&SWR's locomotive stock was its aversion to tank engines. Until very late on in the company's history these were used only when circumstances absolutely demanded it.

The very first engines of the GPK&AR were named but soon after received numbers. As the GD&CR was always intended to merge with the former its engines were allocated numbers following on from the GPK&AR sequence.
From 1851 new engines were given the numbers of older engines that had been withdrawn from service. Eventually new engines were being allocated the numbers of old engines that were intended for withdrawal but which were still running and so two engines would be running with the same number. In 1878 Hugh Smellie introduced an âÂÂRâ list to cater for older engines whose number had been allocated to a newer one. Later on Manson used an âÂÂAâ list system, where the older engine had an âÂÂAâ added to its number. By 1919 the system was so complicated that there was a complete renumbering of all engines.
Class numbers were the number of the first engine built in the class. Given the policy on numbering this meant that classes with lower numbers could frequently be newer than higher numbered classes.

Various shades of green provided the basic colour of the locomotives, with lining in black and white or black and yellow.
The G&SWR locomotive stock fell foul of the London, Midland and Scottish Railway policy of standardisation following the grouping. Within ten years nearly 80% had been withdrawn from service and only a single 1 Class 0-6-2T engine remained by nationalisation in 1948.
