Fitted with Belpaire firebox. Used for shunting (switching) and local goods (freight) traffic..Data from "Locomotives for the Lancashire & Yorkshire Ry - Designed by Mr B Wright", The Locomotive Magazine, Vol VIII (7 March 1903), p. 164.
As noted in Locobase 9140, this was a large class of goods engines built to a common design. There were differences, however, between the first 72 shown in 9140 and the much larger group described here. Although, the boiler was just a bit smaller, the grate was just a bit larger, as were the driver diameters. The boiler pressure increased by nearly 15%. Beyer, Peacock built 80, the first 50 of which arrived in 1881. The later 30 (works 2831-2860) came on the road in 1887. Vulcan contributed 65 (works numbers 871-895 in 1880, 969-988 in 1881, and 1198-1217 in 1887. Aspinall ordered still more under his superintendentship. Of the earlier batches, almost all were later converted to 0-6-0 saddle tank locomotives. The design always seemed "slight" compared to Aspinall's later creations, says Steamindex, but it nonetheless salutes the design: "More importantly, the class demonstrated (1) standardization could be achieved via a multiple builders; (2) at last the railway had a robust freight locomotive (which lasted almost to the end of steam); and (3) was more powerful than the Ramsbottom DX type. On page 86 Marshall notes that Low Moor iron was specified for boiler construction."
Data from Mr Edward Woods, Address to the Institution of Civil Engineers 9 November 1886 (London: ICE, 1886), p. 63 and steamindex's review of L & Y locomotives ([], accessed 30 January 2008). See also "Locomotives for the Lancashire & Yorkshire Ry - Designed by Mr B Wright", The Locomotive Magazine, Vol VIII (7 March 1903), p. 164.
Data from E L Ahrons, The British Railway Locomotive, 1825-1925 (London: Locomotive Publishing Company, 1926); and C J Bowen Cooke, "British Locomotives", (London: Whitaker & Co, 1894)
Successors to the DX, these were bigger engines designed by Sir John Aspinall and produced from 1889 to 1909. The loads taken, said Bowen Cooke in 1894, "...vary considerably, ranging from 15 to 60 waggons (sic), according to the gradients over which they have to travel, which at some parts are as steep as 1 in 27." 63 were superheated beginning in 1912 under George Hughes's direction; see Locobase 16022.Data from "Goods Locomotive with Superheater, L&YR", The Locomotive, Volume 16 (14 May 1910), p. 93.
George Hughes superheated dozens of Sir John Aspinall's powerful six-coupled goods engines (Locobase 3015) beginning in 1909. In addition to drying and energizing the steam, he fitted the existing design with larger cylinders that were supplied through piston valves, and a boiler with a Belpaire firebox and an extended smokebox. Hughes's trials with one of the first new-built engines showed a 10% increase in haulage capacity compared to the older design as well as a 12 1/2% increase in "economy" (whether water, coal, or both, the LM report does not say.)Identical to the much more numerous DX class of the London & North Western.
Ahrons (1927) notes: "[T]he class presented the first example of standardization and mass production of locomotives on such a large scale." Also note that these saw extensive passenger-service use, working the market train between Manchester & Bradford. NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.
