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.
