While on holiday in the Forest of Dean in September 2021, I picked up a secondhand copy of "Gloucestershire Railways in the Twenties" by Humphrey Household. [1] It consists of a review of the development of the railways in Gloucestershire supported by a series of photographs which were predominantly taken in the 1920s by Humphrey Household. The photos are a significant resource. The text of the book is well-written. Its final two chapters were of real interest to me.
