The Slim Gauge Circle is an informal group of over 200 United Kingdom, plus some overseas modellers interested in North American narrow gauge railroads. The Circle was founded in 1982 to provide a meeting place where the emphasis was on modelling, exchange of ideas, meeting old and making new friends plus some trading.  Members interests include Colorado, Maine, logging and mining in various scales.

We hold national meetings twice a year at the L.M.Railway Association Club, Hillmorton, near Rugby, in May and October nominally from 10:00 to 16:00. There are also local area meetings in various parts of the country – see our Meetings page for more information. The Slim Gauge Circular magazine is published twice a year  with Newsletters in between.

There are currently two special interest Modular Layout Groups which meet several times a year, an 0n30 group (SGC – OTT)  and  a H0n3 group (SGC – Hostlars) ,   which are only open to members of the Slim Gauge Circle.

The Circle has a Yahoo group at
