FFESTINIOG Railway (FR) has started a 10-year overhaul of National Trust-owned Hunslet 0-4-0ST Hugh Napier a year early.
The tubes were thin and Hugh Napier was unlikely to see much use in 2020 because of Covid-19.
Having been stripped down no boiler work other than replacement tubes was found necessary, with an hydraulic test anticipated by the end of September.
The chassis has required attention to the wheelsets, horns, slidebars, crossheads and rod ends.
Hugh Napier could operate at FR's October 9-11 Bygones Weekend and during autumn works trains.
