Many thanks to Mike ONeill of Parker, CO for providing some general info on Live Steam track gauges. In the United States and Canada, no one could ever come together and "standardize" on what certain scale gauges should really be, which was unfortunate. Some examples: The standard gauges as adopted by the NMRA years ago for the small live steam railroads are--- 2 1/2 inch (1/2" scale); 3 1/2 inch (3/4" scale), and 4 3/4 inch (1" scale)... In the UK and Canada, 5 inch gauge represents 1" scale...

In the Western U.S. the gauge for 1 1/2" scale is 7 1/2 inch gauge. In the Eastern U.S. the gauge for this same scale is 7 1/4 inches. The same in Canada. Neither gauge is truly correct for the scale involved. For the absolute "purist", the gauge for 1 1/2 inch scale works out to 7 1/16 inches.

This is really a shame because Live Steamers in different parts of the country are "restricted" on whose tracks they can visit and run on. Many years ago, one of the older GGLS members in Oakland, CA built an absolute stunning model of a STEAM locomotive as well as a Steeple-cab locomotive that drew power from either Overhead wire or outside 3rd rail (a 'la SN) and a large beautifully constructed wood caboose. His name was Louis Lawrence and he resided in West Oakland. However. he could ONLY operate his beautiful creations in his own backyard. Why ?? Because for some strange reason he built them with a track gauge of 6 3/8 inches.

The track gauge on Erich Thomsen's "Redwood Valley Railroad" was originally 12 inches before he enlarged it to the current 15 inches.

Anyway, even with early-day intervention by some of the IBLS secretaries, the gauge drama still lingers on. If you are a Live Steam hobbyist, you RUN where you can.
