Manufacturer description

The London and South Western Railway B4 class was a class of 0-4-0 tank engines originally designed for station piloting and dock shunting. They were later used extensively in Southampton Docks for nearly half a century.

The locomotives were designed by the London and South Western Railway (LSWR) Locomotive Superintendent William Adams. They were unusual in having inside Stephenson valve gear but outside cylinders and coal bunkers on the footplate inside the cab. The class were originally built with Adams's design of stovepipe chimney, although these were later replaced by a lipped version, as on our model, designed by Adams' successor, Dugald Drummond. Our model is an example with an original cab, but some examples also had cut away cabs to improve visibility. They were designed for shunting in locations with a sharp curves, such as the dockyard at Devonport and as pilots at the major stations.

The prototype, LSWR B4 class, were 0‑4‑0 tank engines designed by William Adams for station piloting and dock shunting. Built between 1891 and 1908, a total of 25 were produced. They featured inside Stephenson valve gear, outside cylinders and foot‑plate coal bunkers, and were originally fitted with stovepipe chimneys later replaced by a lipped design by Dugald Drummond. The class was employed extensively at Southampton Docks and other locations with sharp curves, such as Devonport dockyard, and operated for nearly half a century. The model depicts the original cab configuration, although some examples were fitted with cut‑away cabs for better visibility.
