37501 Teesside Steelmaker approaches Wychnor Junction on 23 October 1989 with the 6M01 Lackenby to Wolverhampton steel train. Spending just short of a decade as 37501, this loco entered service in 1961 as D6705, acquired the number 37005 with the introduction of TOPS, and finished up as 37601. The very poor lighting here required the use of the long defunct Kodachrome 200 film, which despite being very grainy and prone to odd colour shifts was virtually as sharp as its slower stalemates, and the only fast 35mm film that I found to be of any practical use.
