From the late 1940's right through until the railway changed into Ellerton hands most of the tickets were sold "on the train" by travelling guards/conductors who used to sit on the small "dickey" seats by the brake wheel on the open articulated coaches. Sun or rain you'd find them sat there except when the train consisted of totally closed coaches, then the guard would be inside somewhere towards the back of the train.
Each guard was entrusted with 4 pieces of company property to effectively carry out these tasks and the following images show the money bag, ticket rack, Bell punch (used by early guards) and ticket clippers (that replaced the Bell punch).

The fourth item carried was the magic wallet, with which a skilled guard could keep a compartment of noisy kids quiet for a good part of the journey. Into these all the bank notes collected or offered in change were placed, before the wallet was placed in the money bag with the coinage carried.
The Fairbourne Railway issue magic wallets were all plain black but instead of trying to describe them, extensive research has found something better. Click the link to see the the magic wallet in action:
