Dresden gauge. It meter gauge rail never very widespread in India; examples include the private network used by Coal India's collieries near Nagpur, the works of the engineering firm Larsen and Toubro at Bombay, etc. This section mrter initially built as Broad Gauge. Standard or Metre Gauge 1. Goods taken off at Karachi port had to be first transported km north to Lahore and then east ward to rest of the Indian states.

And the origins of standard gauge for railway use trace back to one railway engineer, albeit an influential one: George Stephenson.

And finally, Roman roads outside of cities were often paved in gravel, not stone, and ruts were mainly a feature of locations with close clearances e. There is, however, a somewhat indirect relationship of standard gauge to historic trends for wagon design.

This covers the range of most larger-gauge railways as well, although there have been both larger broad gauge and smaller narrow gauge spacings used.

Many ancient societies cut ruts in stone-paved roads to guide wagons where safety e. The Romans used ruts in urban streets to guide wagon wheels past the stepping stones used at intersections for pedestrian crossings. These were primarily for delivery wagons as vehicle use in cities was generally prohibited during the day and Romans either walked or were carried in lecticia litters. So even in Roman design, there is no reason to believe that there was a single standard in use.

Certainly there is evidence that for thousands of years, many different civilizations have found approximately 1, mm to be a good spacing for wheels on a variety of vehicles. However, it was approximate at best, and you could say the same thing about five feet 1, mm, another common rail spacing.

Many early railway vehicles were built by existing carriage-makers and were simply wagons or carriages with their wheels replaced, so the size of vehicles chosen by a given railway may have dictated their rail spacing. In the early days a variety of gauges competed, and even today lots of other gauges are in use.

As Wikipedia will tell you, Standard Gauge is in use by more than half the railway lines in the world. But when railways were just getting started, things were a lot more free-form, because each railway line was seen as an independent system. By the middle of the nineteenth century people had begun to settle on country-specific standard gauges. The U. Often these were railroads in isolated areas, either specific to an industry e.

In the U. Britain used narrow gauges in a number of colonial regions. Today, 1, mm is the second most common railway gauge. In the absence of good roads, and few roads at that time were more than cart tracks, a railroad was essential to the economic prosperity of a region, or to getting at resources from remote forests lumber or mines coal, iron, etc.

It costs less to build a railroad with rails closer together: cuts and fills are smaller, bridges use less wood or iron, and curves can be sharper, which avoids other costs of construction.
