Possible; but Doncaster certainly seemed to return to service other classes without repainting blue; the baby Deltics seemed also to retain green after a works visit, though probably their short likely future may have been a factor. The other main work was shunters and I have a photo of a Blackstone in green with a double arrow, but this might have been just a panel swap, and that class, too, had a small life expectancy.strang steel wrote:I wonder if this might have been due to the re-engine programme, which would have meant most of them would not have been due for a major overhaul until well after the blue era began?1H was 2E wrote: Doncaster seemed to prefer "touch up and revarnish" (TUV) of the green but applied the corporate double arrow and the new typeface for D and numbers (in white) to it. Brush 2s (all maintained at Doncaster) in blue were noticeably rare for a quite a while after 1966.
As regards electric locos; the original AC locos (and Woodhead electrics after transfer of maintenance to Crewe) were painted in a "truer" blue originally, and of course this is different to corporate blue. My (edited out) post was to ask the question whether the AL6s (and, indeed, contemporary repaints of AL1-5) after 1965 were in electric blue or corporate blue; I have a couple of photos of A:L5 and AL6 which appear to be in corporate blue though they retain the raised chromium letter/numbers and lion. The AL6s were being introduced as part of "Britain's New Railway" (sorry, East Coast fans) and it's surprising that tha full modern image was not adopted.
And here's another style of the late sixties; blue, white numbers, neither BR crest nor double arrow (and blue roof and red buffer beams) Pretty sure these were done at Toton; not sure that this was corporate blue. This interregnum never seems to get remembered; but, to be fair, most enthusiasts had more pressing targets for their cameras than freshly painted diesels in 1967-68.
