What is considered narrow gauge?
What is considered narrow gauge? A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than 1,435 mm ( 4 ft 8+1/2 in) standard gauge. Most narrow-gauge railways are between 600 mm ( 1 ft 11+5/8 in) and 1,067 mm (3 ft 6 in).
Why does Japan use narrow gauge?
Clearly, it is safe to assume that Japan's choice of the 3'6 narrow gauge was based more on the cheaper construction cost than on the demands of topography. Norway gradually replaced its narrow gauge track with standard gauge but Japan did not take this road because of economic and military considerations.
What is the difference between a meter and a gauge?
An example of a meter is a parking meter where it shows you how much time you have left. Gauges also measure how much of something we have. Gauges are most often used in situations where the thing we are measuring changes all the time, such as in the measuring of volume of something we are using.
