LB&SCR D2 Class

The LB&SCR D2 Class was a series of inside-cylinder 0-4-2 passenger tender locomotives designed by William Stroudley and built at Brighton Works from 1876, used on the London, Brighton and South Coast Railway's secondary passenger services and branch working where the larger Gladstone express engines were not required. The 0-4-2 wheel arrangement was Stroudley's preferred configuration for passenger tender locomotives, using the trailing axle to support the firebox weight while the four coupled driving wheels provided adequate adhesion for the lighter passenger duties the D2 was designed to handle.

The D2 Class occupied the niche below the B1 Gladstone in the LBSCR's passenger fleet: a capable secondary passenger type for the semi-fast and stopping services on the Brighton main line and the Sussex coast branches. Stroudley applied his characteristic Improved Engine Green livery — the yellow ochre that distinguished all his passenger locomotives — to the D2s, and the class had the same neat, well-proportioned appearance as his other designs.

The D2 Class gave service through the late Victorian period before being superseded by Billinton's more modern types. None was preserved.
