Colin - hope it's OK to add this to your thread, but it's where the original discussion occurred...
Stationmaster - of course you were right and Amazon was wrong. Bought my copy from Kevin Robertson at the Southampton show yesterday, and asked him about the discrepancy on Amazon. Apparently the intention was originally to document 1946 through to closure, but so much new material from the earlier years came to light during research that the whole life of the line is now covered. The title is officially "The Didcot, Newbury and Southampton Railway: a new history 1882 - 1966", it now runs to 328 pages, and the price is £38.00. ISBN is the same.
Had a flick through last night, and am hoping to start reading properly this evening. Worth every penny, in my opinion (usual "satisfied customer" disclaimer applies).
Best Regards,
ZG.
