Built by N.A. Dadd & Son for the Door Valley Tramway in 1888.

YEOMAN is the work of Francis Dadd, Norman’s son. Norman retired from the business in 1885.
Francis built a much more modern machine than PRINCESS, taking into account the issues that became present with the older locomotive. An overall roof for greater crew protection, a much-simplified boiler and Marshall’s valve gear are obvious changes.
The engine also boasts a well-tank, offering a lower centre of gravity, while giving a rigid box frame and good access to the motion from both above and below the footplate.

YEOMAN arrived at Door in 1888 and immediately PRINCESS was returned to Dadd’s for overhaul.
YEOMAN was subsequently overhauled by Robson’s of Bray in 1912, & 1936.

When the Door Valley closed in 1965, Rose was offered all the stock. YEOMAN was in a reasonable condition and was returned to steam at Boot Lane in 1970.
