I had a great day yesterday whilst at the London Transport Musuem Depot open day aswell as the old fashioned underground stock (1938 was the best I went in!) there was a 4COR, that made my day even went inside the unit and cabbed it and had my hands on the controls as the staff were so friendly and it had been restored to the good old 60s condition and the seats were one of the best ones I have seen and so comfy!
I will get my mate to send some pics to me and I'll than upload 'em!
Theoretically there's no reason why they couldn't - a slammers no different from any other MK1 - so they should allow it ! In the meantime, there's always Hastings Diesels which give an idea of proper Southern Region comfort. Have you ever been on one of their tours?
Yes, I think those ones with the larger guards van were originally from Tyneside, rather than Merseyside - though I've never been on one as they weren't in passenger service by the time I was on the scene.
