I am back, no thanks to BT's Infinity!
So much interesting stuff thank you all, always nice to get a drivers perspective too.
So Matt, The only Eden Vale I know is a very good ale from up Carlisle way, highly recommended. I believe the coal merchant was G.W.Talbot, at least that is the name mentioned with a photo of the 04 shunter on Flickr. The green 08 was 08011 'Haversham' and a local celebrity it would seem, this page tells the story http://www.leightonlogs.org/08011locostory.
Caradoc, nice find! I will have to seek out that book, I wonder how long that traffic lasted? Not long it would seem.
HMRSPaul, interesting stuff, I have already purchased some photos of the Ermefer tanks from your site, but missed the others. I Don't suppose you know what the freightliners were doing there?
Junction3, So the 25 would come light engine from Bletchley to pick up the wine and coal from Risboro', seems like a long trip for a small number of wagons.
With regard to the underground stock, was it just delivery of 1983 stock or did other rolling stock pass through also?
Thanks again for all the info. Barry
