Sad news indeed.
This from the Daily Telegraph...
Colonel Michael Cobb, who has died aged 93, was a regular Army officer who in retirement produced the definitive historical atlas of the railways of Great Britain, becoming on the strength of it the oldest person ever to receive a PhD from Cambridge University, at the age of 91.
The Railways of Great Britain - Historical Atlas is a wonderful piece of work, useful to professionals and enthusiasts alike.
If you ain't got one - buy one now.
If you have one, then buy another!
Good effort Colonel Michael Cobb and requiescat in pace.
