Thanks everyone, This is my next logical question.
If you have a 9 mile single track line, how long would it have taken to lift it in 1967/68 once they (BR) decided to do it?
Would two months be about correct - I have an email stating they were lifting the down line Sept/Oct 1965 - but it doesn't state if they simply began lifting it, or they had completed it in two months.
My problem is loco 48218 - it was withdrawn 30/9/1967, and there is a photo of it as the "works train probably the last engine to run on the line as they lifted the track" - but no date for the photo!
If 48218 was withdrawn 30/9/1967, the up line must have been lifted between August and September 1967 - would BR really time that to an engine being withdrawn? or do you think by the end of September they had finished and found no other use for the engine more likely?
I know this is not strictly about signalling on a signalling forum - but a lot of you here know a lot more about railways than I do, and I think a lot of will find this an interesting question!
By the way, 48218 was sent to Cashmore's Great Bridge Feb 1968 and scrapped.
