Why Did Japan Choose the 3'6" Narrow Gauge?

2020-7-27  The mine owners therefore decided to mechanize the mine railway themselves to guarantee access to the nearby port. In 1864, Festiniog Railway started operating on a 2' narrow gauge (600 mm) and was hauled by a B-locomotive. Before the mechanization, the mine carts had used gravity to roll downhill but had been hauled back up separately by horses.
