We are a society of like minded enthusiasts who enjoy all aspects of narrow gauge railways and narrow gauge railway modelling. Most of us create models to exhibition standard and in a variety of gauges and locations and the societies members have interests in several items of narrow gauge rolling stock and locomotives.

The Society is best known for our specialist narrow gauge annual exhibition ExpoNG which is one of the largest shows of its kind in Europe but we are also known for organising enthusiasts trips abroad on which many friends join us.

Please have a look around our site and if you would like to come along to one of our weekly meetings please get in touch with us using our contact form - and perhaps if you are interested you might considering joining our society - we always warmly welcome new members of all ages, backgrounds and abilities


Every year the Society hosts quite possibly Europe’s largest specialist Narrow Gauge model railway exhibition - Expo Narrow Gauge®. It was the UK’s first exhibition dedicated to Narrow gauge railway modelling.  We have a dedicated website with information on exhibitors and trade stands for the next event along with travel and other information: Expo Narrow Gauge model railway exhibition.

Greenwich Couplings

Many members of the Society model in 4mm scale and on 9mm gauge track (commonly known as 009) and through many years of testing different coupling systems available the members decided to design their own 009 coupling system. This is known as Greenwich couplings and can be found being successfully used on many layouts around the world.

Find out more about our coupling system with a video tutorial on how to make them.
