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 next edition of Steam Chest is in preparation but delivery may be delayed owing to personal circumstances.
Events in 2015: You can view these by looking on our Programme. NB The planned rally at Leatherhead has had to be cancelled owing to an urgent need for track repairs/rebuilding. It will now be hosted by the Romney Marsh MES at their Rolfe Lane site.

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.
