We are currently working on a new article for the TTG Website that will specifically focus on the 1961 Summer Working Time Table (12th June to 10th September 1961). Lots of information has come to light during our research, but we are now actively seeking details relating to Grantham 34F Locomotive Diagrams for the A3 Pacifics at this time. Another avenue of our research covers the engine changes on express passenger trains at Grantham during the same period, so if you can assist with any of the above please do let us know.
Thanks - The TTG Team
