The London, Brighton and South Coast Railway E3 Class were 0-6-2Tside tank steam locomotives. Seventeen were built and they were designed by R. J. Billinton as a development of an earlier design by William Stroudley.
In the summer of 1889 Stroudley designed a class 0-6-2 radial tanks to replace his earlier E1 class 0-6-0T for short-distance goods and shunting duties. However, only one locomotive was under construction at the time of Stroudley's death. R. J. Billinton order further work to be delayed whilst he made detailed modifications. This locomotive, No. 158 West Brighton appeared in traffic in 1891, and was originally classified as F class, but later re-classified as E3.
Once the original teething troubles had been rectified, Billinton ordered a further sixteen locomotives to a broadly similar design. These entered traffic between November 1894 and December 1895. All were rebuilt with new boilers and extended smokeboxes from 1918 and some had increased boiler pressure. Cylinder diameter was reduced from 18 to 17.5 inches (457 to 445 mm) by the Southern Railway.
The prototype No. 158 was withdrawn in 1934, but the remainder all entered British Railways service in 1948 and were numbered 32165–32170 and 32453–32462. The final E3 was withdrawn in 1959 and none survived into preservation.
