Each year CARM has produced a calendar that is sent to each of the members, one per membership, as a member benifit. The calendar uses a spiral binding so that each one half of the 2 opposing pages is devoted to one month of calendar and the page has a member submitted image of either a proto or model railway scene. The images are divided evenly between prototype and madel images, 6 of each. These are printed in full colour and have a heavy bond front and rear covers. The cost of the calendar is included as part of the membership.
