Sneyd Colliery, Burslem Beyer-Garratt Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 502)

Data from Wiener (1930) and Gavin Hamilton's excellent compilation of Garratt data posted at [link] . (6 September 2005). See also Andrew Howard, "Potteries Loop Line - Background, Description and Train Services", accessed 16 January 2018 at [link],%20Description,%20and%20Train%20Services.pdf; and Fred Hughes, "Explosion at Sneyd Colliery on New Year's Day 1942", on the Potteries.org website, last accessed 16 January 2018 at [link] . Works number was 6729 in 1931.

This was one of three standard-gauge Garrtts produced for British industrial users to the same design as the first (Locobase 641).

Howard's account of the well-traveled Loop Line includes a description of the Sneyd Colliery operation, which he notes had been open since the 18th Century. Sneyd Colliery Ltd was formed in 1900 and "was a progressive and well-equipped operation and it was unfortunate that it was the site of the worst mining disaster in North Staffordshire". [thepotteries.org story by Fred Hughes describes the internal explosion that killed 57 men and boys on 1 January 1942.].

Howard wrote that the internal Sneyd Colliery line crossed the Loop Line at two points and the internal line, challenged by a sloping site, occasionally presented 1 in 20 (5%) grades. The 3 generated the power necessary to "do the heavy shunting."

It was scrapped after 1962.
