Here's one of my favourite shots - in fact the first two are pretty good. The first is LT 1938 stock on the Bakerloo line, heading for (and very near) Stonebridge Park. I used the Bakerloo for many years to get to the smoke and rode these tube trains innumerable times, never thinking of them as worth a photo. The date is 1982 and it's passing Willesden TMD. On the right hand side of shot is an overhead wiring train, doubtless retained at Willesden for maintenance.
Back to Willesden High Level, again in 1982, and a Class 501 heading for Richmond on the North London Line. Again familiar stock to me as I used it many times to travel from Harrow & Wealdstone to Queens Park for school swimming lessons.
1982, and as Yorkie Dave pointed out, Manton Viaduct where it crosses the Chesterfield Canal and MGRs From Worksop to ECML in 1982. Loco is 56086. According to Rail UK it was withdrawn at the end of September 2008 and sold to Shackerstone. It was reinstated at the very end of 2011, or maybe August 2012 and sold to Europhoenix.
Again at Manton Viaduct where it crosses the Chesterfield Canal two light class 20s, Worksop area. 1982. I read these as 20092 and 20017. 20092 was born as D8092 and, according to Rail UK was withdrawn on 5 December 1982 and reinstated on 17 April 1983. It remains in service. 20017 was D8017, withdrawn from Tinsley in December 1982 and cut up at Crewe Loco Works in February 1984.
