A fab little book which explores the origins of every Tube and DLR station name. The amazon reviewer gives a typical entry:
"DEBDENtakes its name from a natural location of the area and is recorded as Deppendana in the Domesday Book. It is derived from the Old English DEP, 'deep' and DEN, 'valley' - which means simply 'the deep valley'. It was recorded as Depeden in 1227. The station was opened by the Great Eastern Railway as Chigwell Road on 24 April 1865, and re-named Chigwell Lane on 1 December 1865. It was again renamed as Debden on 25 September 1949 when first used by Underground trains."
It's great how you get other information including the year the station opened, and the name changes that have since occurred. There's also black and white photos of many of the stations or their immediate surroundings.
I also like the cover with the strange mis-spelling of station names - "Holeburne" "Pynnor" and "Dolly's Hill". A bargain at £4.95.
