How large is a Large Scale Train?
7/8n2 is the newest and largest of the "garden" railway sizes. It has been developed in the past few years by modelers who use "G" gauge (45mm) track, running correctly scaled models of two-foot narrow gauge trains. The proportion of 13.7:1 is 50% larger than 1:20.3. In 7/8 scale the track gauge of 1-3/4" equals two feet, thus 7/8 of an inch to the foot.

Railways in 7/8n2 are divided into two categories: First are the industrial, plantation, logging and "critter" railways which are patterned after smaller prototypes, which typically have 4-wheel, short wheelbase locomotives and cars, or geared types of steam locos. These include Welsh slate quarry lines, peat bog, brick yard, sand pit and sugar cane railways. The advantage to the smaller 4-wheel 7/8n2 trains is that they may be operated on existing tight radius tracks with few modifications.
Second, are the Maine prototype two-foot models which "main line" in appearance, and can reach lengths of 24-30 inches for a 8-wheel freight car, with locomotives such as the Forney types or small 2-6-0 and 2-6-2's. These lend themselves to live steam operation and can weigh over twenty pounds. The Maine two foot models in 7/8 scale require 12 to 16 foot radius curves whereas the industrial railways can run on 5 foot radius.
7/8n2 is an evolving segment of the large scale hobby. There is great appeal in trains which are robust sized versions of tiny prototypes. This allows for maximum detailing and for models which really stand out in the crowd. At present no true 7/8n2 locomotives are available commercially, although several are in the planning stages. Small industrial switchers can be upsized from a variety of commercially available 4 wheel locos, with larger cabs and 7/8 scale details added. Trucks and parts for Maine type freight cars, and 4 wheel cars are available as are kits for basic 4-wheel rolling stock. A wheel standard has been developed which follows prototype practice, with a wider tread than any G scale wheel, yet designed to run on track compatible with 1:20.3, 1:22.5 and 1:24 models. Rail codes 332, 250, 215 and 195 and track components are also compatible with 7/8n2.
A small but growing number of 7/8n2 railroaders are happy to help, explain and share their unique perspective on large scale model railways.
