1962. D35 and coaches breast the top of Lickey at Blackwell. The working is possibly for crew training given the number of people in the cab, and lack of train reporting number. Given the condition of the loco, I suspect this is Spring 1962, with leaves on the trees, so possibly just before the June timetable change...I doubt it is the previous Summer as the loco only entered traffic on 30/06/61 allocated to Derby...on 19/08/61 it was reallocated to 82A Bristol Bath Road, the shedplate seen on the photo attesting to this.
