Here is the history of the E2-Class Tank Engine from the London, Brighton, & South Coast Railway. In 1910, the Stroudley E1s were out of date and worn out. By this time, though, only one E1x rebuild had been completed by D. E. Marsh. Billinton designed a new class of locomotive, the E2s. They were supposed to be a lot better than they were; they were designed to haul small freight trains and small push-pull passenger trains. In June 1913, L.B.S.C.R. completed their work on the number 100, the first E2. Over the next eight months, numbers 101–104 were made. The first five did not have extended side tanks and had a very small bunker, and had a superheated boiler. So, they had a limited range of about 50 miles. They were trialed on everything, and there were only two things they were good at: shunting (switching in America) and small freight, like the E1s and the A1s/A1xs. Billinton tried to fix the issues; in June of 1915, number 105 rolled out of Brighton works. (Also, this is when Thomas the Tank Engine was supposedly built as number 105 or 106.) Number 105 had extended side tanks but did not fix the bunker problem. 106–109 more were built in 1915–1916. In 1920, it was combined into the Southern Railway, and they were renumbered to 2100–2109. No experiments were carried out on them. During WW2, they were used for shunting at King’s Cross, Paddington, St. Pancras, and Euston. After WW2 they were renumbered again to BR 32100–32109. They were trialed at Southampton Docks in 1953, where the S100s were located, and they were perfect for shunting. They were scrapped in 1961–1963 after the British Rail Class 07.
