The S100 is a side tank designed by Col. Howard G. Hill.
In 1942, the USATC ordered 382 S100s from Davenport Locomotive Works of Iowa, H. K. Porter, Inc, of Pittsburgh and Vulcan Iron Works of Wilkes-Barre. They were shipped to the British War Department in 1943. They were stored in Britain until 1944. After D-Day, most went overseas but some remained in store.
After the war, The Southern Railway bought 15 S100's (14 for operational use and one for spare parts) and designated them USA Class. They were purchased and adapted to replace the LSWR B4 class then working in Southampton Docks. SR staff nicknamed them "Yank Tanks".
For fifteen years the entire class was used for shunting and carriage and van heating in Southampton Docks. They performed well and were popular with the footplatemen, but the limited bunker capacity often necessitated the provision of relief engines for some of the longer duties. Two examples were fitted with extended bunkers to address this problem in 1959 and 1960, but a more ambitious plan to extend the frames and build larger bunkers was abandoned in 1960 due to the imminent dieselization of the docks. They also often suffered from overheated axleboxes which was less of a problem when shunting but prevented them from being used on longer journeys.
A more serious issue was the condition of the steel fireboxes originally fitted to the class which rusted and fatigued quickly. This was partly due to their construction under conditions of austerity, and the hard water present in the docks. This came to a head in 1951 when several had to be laid aside until new fireboxes could be constructed. Thereafter there were no further problems.
During the mid 1960s six examples were officially transferred to ‘departmental’ duties and renumbered. These went to Redbridge Sleeper Depot (DS233), Meldon Quarry (DS234), Lancing Carriage Works (DS235 and DS236), and Ashford wagon works (DS237 and DS238; where they were named Maunsell and Wainwright).
Nine examples remained in service until March 1967[24] and five of these survived until the end of steam on the Southern Region four months later. Two of these engines, 30065/DS237 and 30070/DS238, were sold to Woodham Brothers in South Wales in March 1968. However, before they could make their journey, their bearings ran hot and were declared "unfit for travel" which led to the two tank engines being dumped at Tonbridge. Five months later, they were taken to Rolvenden when they were purchased for preservation on the Kent and East Sussex Railway.
At the moment, both locomotives are o.o.s. with no date known for return to traffic, ironically, it is the condition of their fireboxes which gives concern.
