Class T3 Details

Grouping : Southern Railway
Configuration : 4-4-0
Common Name :
Designer : William Adams

The LSWR T3 class was one of the family of four similar express passenger 4-4-0 steam locomotives designed for the London and South Western Railway by William Adams. Twenty were constructed between 1892–1893. These four classes represented the pinnacle of his career and were at least on par with, and in many cases better than, contemporary locomotives of other lines. Although each of these four classes had outside cylinders, which tended to lead to unsteadiness, these locomotives had long wheelbases and always ran freely as well as being powerful for their day.

The first 20 locomotives were built with 7 ft 1 in driving wheels and were numbered 557–576, and had been intended as a variant of the X2 class with with longer smokeboxes, smaller bogies wheels and slightly smaller driving wheels (6 ft 7 in or 2.007 m versus 7 ft 1 in or 2.159 m). Adams chose the smaller sized wheels as the locomotives were intended for use on the undulating lines west of Salisbury. However, upon completion of the class by 1893, some were sent to major depots on the Bournemouth line, as well as those on the Salisbury-Exeter route. In reality, the coupled wheelbase was lengthened by 6 inches (150 mm) and the locomotive was fitted with a firebox 6 feet 10 inches (2.08 m) deep – the largest firebox of any of Adams' designs.

Drummond gradually replaced the elegant stovepipe chimneys with one of his own design, but as these and other minor modifications took place under Drummond's care, the T3s were being displaced by more modern designs such as his T9 class. A few T3s were sent west of Exeter where they were particularly successful. During the First World War, these T3s, like all of Adams locomotives, were in much demand and all survived to be taken into Southern Railway stock in 1923.

With the spread of electrification in the 1920s and 1930s, a surplus of light passenger locomotives on the LSWR and SR was building up and withdrawals of the T3s commenced, with all but three going by the end of 1933. One of the remaining three was withdrawn in 1936, but numbers 563 and 571 saw the start of World War II. However, No. 571 was withdrawn in 1942 having amassed more than 1.7 million miles in service. No. 563 continued in service only to be laid aside in 1945 with over 1.5 million miles in service. It joined the ranks of locomotives outside the works at Eastleigh awaiting the torch, but preparations for the centenary of Waterloo station were under way for 1948 and No. 563 was chosen to represent the old London & South Western Railway. It was partially restored and painted in the early Drummond livery of the LSWR.

All passed to the Southern Railway at the grouping in 1923. Withdrawals started in 1930, and by the end of 1933 only three remained. No. 557 went in 1936, 571 in 1943, and the last, 563 was retired in August 1945 and set aside for preservation. Its permanent home is the Shildon Locomotion Museum in England, but it's in Toronto, Ontario, from May to October, 2011, on loan for use in a theatrical production of The Railway Children at Roundhouse Park.

On the closing of the exhibition, No. 563, together with other exhibits, was stored at the back of Farnham electric carriage shed. In 1958 it was transferred to Tweedmouth for storage until the 'permanent' home of the BTC Museum at Clapham was established. In due course, this was closed and Nš563 was sent to the new National Railway Museum at York, where it is on permanent display in Drummond's 1903 livery.
