Keeping the spirit of the past alive for tomorrow
and looking to the future.

The National 2½ Inch Gauge Association is a not-for-profit organisation.

The latest edition of Steam Chest (SC146) was printed and posted out in late September. The link to it has also been emailed out. The file is 80MBytes so takes a while to download.
Events in 2015: You can view these by looking on our Programme. A Midlands Area Get-Together has ben arranged for Saturday October 10th, hosted by the North West Leics club, where there will be plenty of room for exhibits and you can run a loco as well if you want to. There is free parking on site.
The 2016 Calendar has been created and 50 will be printed in early October. Please email the Publications Officer to reserve one or more. Be aware that his move is now imminent, so the published phone number will cease to be valid after 10th October.
Our 40th Anniversary Celebration mugs can be purchased from Roger Palmer.

About us

Following concern about the availability of plans, castings and tracks on which locomotives could be run, Paul Wiese arranged for a meeting in May 1975 to which all interested parties were invited. The result was the founding of the Association, the stated aims of which were to promote interest in the gauge.
The Association now looks forward to the future knowing that the interests in this historic scale are safe.

About 2½" gauge

Sometime around 1900 a set of track gauge standards was formulated. Thus tracks with a dimension of 2.500 inches between the inner rail edges was designated "GAUGE 3". At that time, this gauge was fairly popular for garden or scenic model railways, with the engines using clockwork or meths powered. Certainly none of them were capable of hauling the driver, let alone a driver and passengers ! Such capabilities arose from the work of (arguably) one man, Lilian (Curly) Lawrence, who wrote under the pen name of LBSC. Initially, the scale used for standard gauge locomoltives was half inch, but this was changed to 17/32-ins. (about 13½mm) very early on. A typical loco and tender is 3ft long, and looks very large when stood next to OO or O gauge models. Narrow gauge locomotives are beginning to become popular and drawings for such designs as the Lynton & Barnstaple Manning Wardles and the Leek & Manifold engines are in preparation. Drawings for the Hunslet Quarry engine "Penrhyn" can now be purchased, and the castings required should be available in the New Year. Electric powered locomotives are becoming popular and these too have been or are being developed. The Association has promoted two coal-fired locomotive designs suitable for beginners.
