5" gauge William Adams Class 460
Assembly & Overview
  5. Overview  
The LSWR Class 460 was a seriesof 21 express passenger 4-4-0 steam locomotives designed by William Adams for the London and South Western Railway (LSWR), with 20 units built in 1884 and one additional locomotive constructed in 1887 for display at the Jubilee Exhibition. These locomotives represented an evolution of Adams's earlier 445 Class, featuring larger 79-inch driving wheels to enhance performance on high-speed express services across the LSWR network, while retaining similar boiler and cylinder dimensions for compatibility and efficiency. Built by both Robert Stephenson & Co. and Neilson & Co., they were numbered 147, 460–478 and 526. Key specifications included 18 x 24-inch cylinders, a boiler pressure of 160 psi, Stephenson valve gear, and a tractive effort of 13,387 lbs, enabling them to haul passenger trains effectively on the expanding LSWR routes during the late Victorian era. The class's design emphasized speed and reliability for intercity expresses, such as those between London and Southampton. All were withdrawn from service by 1928.
I started this build during June 2026 working to drawings supplied by Kenions and, all being well, expect to take two to three years to complete it.
