There are plenty of Narrow gauge railroads across the US but there aren't that many 2 foot (610 mm) narrow gauge railroads around. Ironically, this was the chosen gauge railroad width for the cooperative allied forces of World War One because in order to supply troops at the front in their trenches, the allied nations needed a narrow gauge rail that was harmonious with Meters and Feet in order that it fit French, British and American locomotives and railcars that were in existence before the war. 24 inches (2 Feet) equaled 610MM. Also, the rail lines that extended forward as the front moved were much easier to lay down with army troop muscle power due to the lighter weight. One last thing. When Locomotives were unavailable, knocked out or out of steam. Mules could pull the train cars along with not much more effort than that of a street car.
