Doll is a 2 ft (610 mm) gauge 0-6-0 T steam locomotive based at the Leighton Buzzard Narrow Gauge Railway in Bedfordshire.

History

Industry

Doll was built by Andrew Barclay Sons & Co. in 1919 (works number 1641), and was one of three identical engines built for the Sydenham ironstone quarries, near Banbury in Oxfordshire. The quarries were closed in 1925 following the takeover by Stewarts & Lloyds Minerals in April 1925, and the three engines were transferred to Bilston steelworks, near Wolverhampton. The other two engines were Winifred (AB1424/1915) and Gertrude (AB1578/1918). Gertrude and Doll worked at Bilston until they were withdrawn from service in 1959, but WInifred seems to have been scrapped before 1939.

Preservation

In 1960, after some negotiations through the avid steam preservationist, Max Sinclair, Doll was moved to the Burton Green & District Light Railway near Kenilworth in Warwickshire, where she was returned to steam in 1962. By 1965, the site at Burton Green was for sale, and the railway was closed. In 1966, Doll was sold to Alan Bloom of Bressingham, and he initially ran here there at Bressingham Steam and Gardens museum. Unsuitable for the gauge of the Nursery Railway, laid to the Penrhyn Quarry Railway gauge of 1'-10.75" gauge (Doll is 2' gauge) and with a long fixed wheelbase, Doll was put to one side at Bressingham, before being sold to the Leighton Buzzard Narrow Gauge Railway, where she moved in 1969.

Doll was temporarily withdrawn from service at the Leighton Buzzard Narrow Gauge Railway in 19??,. at which point she received a new all welded boiler from Bennett Boiler and a full bottom end overhaul at Alan Keef Ltd. The valve gear was fitted with new eccentrics and repined and bushed to remove the lost motion which had developed. It was seen that at some point in the locomotive's past the wear had been compensated for by sawing part of the lap from the slide valves and filling in notches in the reversing quadrant near mid-gear. After repair the engine returned to LBNGR and was in regular use from 2004 until the boiler tubes gave out prematurely. It is now undergoing another overhaul and it is expected she will back pulling trains in the summer of 2017.
