What are the disadvantages of narrow gauge railway?
A narrow gauge has, in addition to cost advantages, a capability for sharper curvature; among its disadvantages are reduced lateral stability and consequent loss of operating speed.

Fastest trainsQueensland Rail's Electric Tilt Train, the fastest train in Australia and the fastest 3 ft 6 in (1,067 mm) gauge train in the world, set a record of 210 km/h (130 mph). The speed record for 3 ft 6 in (1,067 mm) narrow-gauge rail is 245 km/h (152 mph), set in South Africa in 1978.
If locomotives were imported from elsewhere, especially in the early days, the track would be built to fit them. In some cases standard gauge was adopted, but many countries or companies chose a different gauge as their national gauge, either by governmental policy, or as a matter of individual choice.
Each company faced unprecedented construction problems—mountains, severe weather, and the hostility of Native Americans. On May 10, 1869, in a ceremony at Promontory, Utah, the last rails were laid and the last spike driven.
The railroad opened the way for the settlement of the West, provided new economic opportunities, stimulated the development of town and communities, and generally tied the country together.
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.
The current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est. The trainset, the track and the cantenary were modified to test new designs.
The smallest rideable gauge is often cited as 2 1/2 inch (64mm) gauge railways, with the track elevated on stilts and the driver / passengers straddling the rolling stock with legs dangling either side.
No.The speed difference between the fastest aircraft and the fastest trains is about an order of magnitude. The atmospheric density at ground level would generate too much drag for a train to go as fast as a typical jetliner, let alone go supersonic.
rather than pay for the expense of maintaining track to a higher standard, and having to maintain the additional cab signals, and having to outfit all locomotives that use the line with cab signals, or ATS, or ATC, the freight RRs simply place the speed limit at 79 mph, and use Automatic Block signal systems.
Today, portions of the original Transcontinental Railroad are still operating. The tracks have been replaced over the decades, but through Utah and Wyoming the routes remain unchanged.
