Auden Type "Knapsack"

The "Knapsack Type" is an industrial class of 0-6-0T tank engines and one of the standard types of locomotives designed by the Reginald Auden Locomotive Company. They were built between 1911 and 1924 and were in service for over half a century with some remaining in service in industrial use until the late 1980s / early 1990s.

The class was develloped from the earler "Customs" Type of 0-6-0 Dock Shunters, with the main difference being the outside valve gear being completely changed for the Walschaerts valve gear rather than the Stephenson Link valve gear allowing for easier maintainance. Other small differences were longer side tanks, a Stirling-Style (GNR) cab and the removal of the smokebox wingplates after the smokeboxes were lengthened. The exact number of locomotives built is unknown, though is thought to be between 90 and 105. They were delivered to various Etorean industrial and light railways. They were used on light to medium-sized local and shunting traffic as well as in freight and passenger traffic.

The class was used by both industrial and private railways with a small number being sold to the GN&SR, the SWR and the ENR. The first of the class were two locomotives built for use at the Seven Sisters colliery in Latterton. The class also excelled at passenger work as no less than eighteen found work on different passenger carrying duties, most being light railways or colliery passenger trains though some of the mainline examples did work branchlines (mostly mixed trains of both passenger and freight vehicles).

The class had a relatively long working life in both industry and on the mainline with seven surviving into preservation.
