Yes, getting very interesting indeed! There certainly do appear still to be some sizeable gaps in our knowledge … and thanks to you guys for assisting as much as you already have done. I haven’t seen the Brian Radford book yet … did it give any further details? As regards 12th to 14th September 1964, the following is my current understanding in respect of those locos that worked beyond the BR accountants’ deadline: Sat 12th - 46228 - My own last sighting of this loco was on Tues 8th September, when it worked 4K00, 04-54am Carlisle-Crewe fully-fitted freight. Quite how it got to Glasgow on the 11th and then back to its home shed at Crewe really does need elaboration. Sat 12th - 46237 - 1A33, 8.40am Carlisle – Euston (Carlisle to Crewe) This would have been the “unidentified green Duchess” and I confirm it was indeed this loco. (I photographed it that day on that train.) Sat 12th - 46238 - Although I was photographing all day alongside the WCML, neither I, nor any of my colleagues observed this loco at all. To the best of our knowledge, its final job was on Friday 4th, when it worked 1S83, the last-ever steam-hauled ‘Caledonian’ - at least as far as Carlisle. Any subsequent sightings beyond that date need clarifying. Sat 12th - 46244 - 1S53, 9-25am Crewe to Perth (throughout) Two friends travelled on this train from Perth Sat 12th - 46245 - 3L09, 10.25am Crewe – Carlisle Parcels (throughout) Sat 12th - 46251 - 3K16, 8.15am Carlisle – Crewe Parcels (throughout) Sat 12th - 46254 - 3L14, 1.40pm Crewe to Carlisle parcels (throughout) Sat 12th - 46257 - Springs Branch MPD to Manchester Victoria for ‘British Railway Queen’ event, then to Preston shed for storage (possibly via Newton Heath) Sun 13th - 46244 - 1M12, 9-50pm (Summer SuO) Perth to Euston (Perth to Carlisle) Sun 13th - 46237 - 3L09, 6.20am (SuO) Crewe – Carlisle Parcels (throughout) Sun 13th - 46245 - 7G02, 5-08am Carlisle to Bescot freight (Carlisle to Crewe) Sun 13th - 46255 - 3M04, 6.44pm Aberdeen to Manchester Oldham Rd fish (Perth to Carlisle) Regrettably, I suspect that very little further new information is now likely to emerge, but I shall keep digging and will use this thread to report anything else that is discovered. Hope others can do the same!!
