Data from "Express Locomotive, NSR", Locomotive Magazine, Vol VI (September 1901), p. 154.
This was described as a rebuilt 2-4-0 from an earlier class that had the tallest drivers on the NSR. In its newer form, as produced by Locomotive Superintendent Longbottom, it had a compact, bustling look. Its driver diameter of 72" likely represents miles of adverse grades for the NSR expresses to scale.
Data from L Longbottom, "Four Wheels Coupled Express Passenger Engine," North Staffordshire Railway", Railway Engineer, Volume 13, No 1 (January 1892), pp 5-6. See also J Pearson Pattinson, British Railways: Their Passenger Services ...Second Editions (London: Cassell & Company, 1893), pp. . (Thanks to Alexander Blessing for his 16 June 2024 email reporting the class size (4), the correct wheelbases, and cylinder stroke. )
Classic British 2-4-0 designed by Luke Longbottom, who named the first two engines John Bramley Moore and Colin Minton Campbell. It was his first design as the NS's locomotive superintendent and proved to be an enduring success.
Compared to other engines of its time, however, it possessed relatively modest proportions and a small boiler, even in relation to its relatively small grate. Like many other British engines of the time, it had a Belpaire boiler, rounded steam dome, and a handsome livery (in this case a dark red). The NSR reported an average fuel consumption "including lighting up" as 31.5 lb/mile (8.77 kg/km).
54--named John Bramley Moore--and 55--Colin Minton Campbell--entered service first. 45 and 46 joined them two years later.
They worked between Manchester and Stafford and between Crewe and Derby. Pattinson described the railway as serving a district known as "The Potteries". In addition to 200 miles (322 km) of railway, the company owned 119 miles of canal. Of the railway's two principal section, the Crewe-Stoke-Burton or Derby section hosted relatively slow 30-mph (50 kph( timed trains. Colwich to Macclesfield, used by London & North Western through expresses connecting Manchester and London, ran at higher speeds over "fairly easy" gradients.
One "very curious train" attracted Pattinson's attention as he examined the July 1891 timetable. "This wonderful train" connected Stoke with Crewe , 15 miles distant, in 45 minutes and allowed solely first-class passengers on condition that they release the company from any liability in case of accident. "Why such restrictions were made we have never been able to ascertain," Pattinson remarked, "and fancy this Staffordshire knot would be a very difficult one to unravel."
54 left the roster in 1905; the other three followed in 1911.
