It was acquired on 1854 by John Lloyd Jones who sold it on to the Darbishire Company, owners of the Penmaenmawr granite quarries, in 1862.

Railway enthusiast Rich Morris began collecting narrow gauge rolling stock in 1963,[2] storing many at his home in Longfield in Kent.

[2] With the closure of Pen-yr-Orsedd, The Festiniog Group offered Morris space for his collection at their largest quarry, Oakeley.

Further collections were brought to Oakeley and the Narrow Gauge Railway Centre was opened in the Gloddfa Ganol tourist attraction.

The Nantlle Railway connection was used up until 1963, while the internal 2 ft (610 mm) gauge lines continued in limited use until the end of quarrying.
