Sir Haydn was built in 1878 by Hughes' Loco and Tramway Engine Works Ltd. of Loughborough as a 0-4-0ST (he is now a 0-4-2ST).


He worked on the nearby Corris Railway until the closure of that line in 1948. In 1951, he was purchased by the Talyllyn Railway, along with the other surviving Corris locomotive, who became Edward Thomas, and was named after the line's late owner, Sir Henry Haydn Jones. The precarious state of the track meant he was seldom used for the first few years, and firebox problems caused his withdrawl in 1957. He re-entered service in 1968.

Sir Haydn is currently running in the guise of Sir Handel as a replacement for Duncan's prototype, Douglas, who is under overhaul.

In April 2012, Sir Haydn will make his second visit to the Corris Railway and will be worked there until May 17th, 2012 when his boiler certificate expires. However, he will remain at the Corris Railway for the rest of the summer as a static exhibit to generate interest in the Corris Railway's plans for their next new-build locomotive; a copy of Sir Haydn. Then, after the summer, Sir Haydn will return to the Talyllyn Railway for his next overhaul.

Sir Handel and Albert, an engine from the Mid Sodor Railway, are based on him.


Sir Haydn is currently painted in the Corris Railway livery of red with purple stripes.
