The Society was founded in Cheltenham in 1928 at a time when there was little official information published about locomotive stock, their allocations or regular duties. The Society set about rectifying this by members writing to each other, the publishing of a magazine and some meetings organised around the country.
The growth of the Society was such that it ran the first enthusiasts railtour in the 1930s but the war years effective stifled both the flow of information and the growth of the Society.
