·
The track gauge used
in the most of the Metros (Delhi Metro, Hyderbad Metro etc) in India is Standard
guage, not Broad gauge.
·
The distance between
the two tracks on any railway route is known as gauge.
·
Standard gauge is 1435 mm or 4 feet 8 ½ inches. It is also called as
uniform gauge, UIC gauge, International gauge etc. 60 % of the World Railway tracks are operated in
Standard guage only.

Smallest guage and
Longest gauge in the World are 15 inches or 381 mm and 7 feet ¼ inches or 2140
mm. That means, Longest gauge is 5.5 times longer than Smallest gauge.
·
The speed of a train
is a function of the diameter of the wheel, which in turn is limited by the
gauge. The wheel's diameter is usually 0.75 times the width of the gauge and
thus, the speed of the train is almost proportional to the gauge. If higher
speeds are to be achieved then the broad gauge track is given the priority instead
of metre gauge or narrow gauge track.
