Tickets issued from British Rail's APTIS system had a considerable amount of detail, presented in a consistent, standard format. The design for all tickets was created by Colin Goodall. This format has formed the basis for all subsequent ticket issuing systems introduced on the railway network – ticket-office based, self-service and conductor-operated machines alike. Much of the following summary is therefore applicable to the other systems featured in the "British railway ticket machines (computerised)" section.
