from 1966 onwards a group of volunteers has been working on the preservation of the corris railway's infrastructure. in 1981 the maespoeth junction site was returned to railway ownership under the auspices of the corris railway society and the engine shed now once again serves its original purpose as a home for the railway's locomotives, and as its engineering headquarters. the engine shed is a grade ii listed building, and successfully attracted a large heritage lottery fund grant to fund re-roofing of both the engine shed and the associated s&t shed.
