"Up class H mineral on the Erewash main line at Stoneyford, near Langley Mill, 1963." Another view northward from the bridge at Stoneyford, exactly as SK4449 : Erewash Valley main line at Stoneyford, near Langley Mill, 1963 and others I took at this spot. This Stanier 8F 2-8-0 is No. 48721: it was one of the many built at the Brighton Works of the SR in the War (8/44) nominally for the LMSR but actually acquired temporarily (until late 1947) by the LNER and employed (together with another 43 built by the LNER) as Class O6. (Class O6 also comprised 60 8Fs (LMS Nos. 8500-59) built at Darlington and Doncaster in 1944-45 and hired, but not purchased by the LNER until 1946-47!) No. 48721 was numbered 7667 when new, then 3116, then 3515 on the LNER, becoming 8721 on movement to the LMSR in 11/47, so its BR number (48721) was its fifth.
