2 foot narrow gauge railroads initially were designed for limited local area mining, logging, freight and passenger use.

Sn2 (wide track version) track is the HOn3 type, gauge .413 or 10.5mm. HOn3 track is approximately 10% too wide to be correct for a 1/64 modeling scale of a 2' narrow gauge railroad. The correct gauge is .375 or 9.52mm. HOn3 track being close in gauge and readily available is considered to be an acceptable standard when modeling to the "wide track version" of Sn2. HOn3 track is available in rail codes of .040, .055, .070 and .083.

Certain Locomotives, tenders and rolling stock are modified to compliment the 1/64th scale. Chassis clearances require specific coupler styles and heights as to the type of railroad being modeled. See the Sn2 standards also see the FAQ standards for differences and compromises when modeling Maine, Colorado and other type 2' narrow gauge railroads in Sn2.
