We are fully paid members of NARM - the National Association of Railway Modellers - who set the standard for all GWR exhibition layouts around the UK. All three of our exhibition layouts meet the official NARM GWR branch line criteria as follows:

​

A GWR branch line exhibition layout will only be considered  exhibition standard if the layout contains:

​

• at least one siding which has a static open plank wagon and at least one banana wagon representing a local dairy. 

• a windmill situated within the vicinity of the station area, no further than 30 inches from the station building. (Powered sails optional).

• at least 90% of the scenic element must be hills and grass with no other features of note. 

• sheep or cattle must be confined to a pen on the branchline platform area.

• layouts must include a Bedford OB single decker bus travelling on a road going over a small bridge.

• Backscene must be Peco market town. Realistic photographic backscenes will not be accepted.​

• Rolling stock must operate to a timetable with a minimum of one locomotive moving at least once every ten minutes.
