After the Civil War, the economic recovery of the southern United States hinged on trade with the North and moving goods westward via the railroad. But there was a problem. Tracks in the South had been built with a gauge (or track width) of 5 feet but the majority of tracks in the North had a 4-foot 9-inch gauge (more or less).
So after much planning, over a concentrated two-day period in the summer of 1886, the width of thousands of miles of railroad track (and the wheels on thousands of rail cars) in the South was reduced by three inches.
Rolling stock, too, was being prepared for rapid conversion. Contemporary accounts indicate that dish shaped wheels were provided on new locomotives so that on the day of the change, reversing the position of the wheel on the axle would make the locomotive conform to the new gauge. On some equipment, axles were machined to the new gauge and a special ring positioned inside the wheel to hold it to the 5-foot width until the day of the gauge change. Then the wheel was pulled, the ring removed, and the wheel replaced.
To shorten the axles of rolling stock and motive power that could not be prepared in advance, lathes and crews were stationed at various points throughout the South to accomplish the work concurrently with the change in track gauge.
Answer:
In both the New England and Chesapeake regions, English colonists established settler colonies based on agriculture, in contrast to French trading posts in Canada. These settlements were based on some form of agriculture and had some measure of self-sufficiency, especially in New England. For example, permanent settlements were established at both Jamestown in the Chesapeake and Boston in Massachusetts Bay. The economies of the New England and Chesapeake colonies were very different. The New England colonies had a more diverse economy which included shipping, lumber, and export of food crops. On the other hand, the Chesapeake colonies' economy focused almost exclusively on the production and export of tobacco and a few other cash crops. This focus on cash crops fostered a need for slave labor in the Chesapeake. As a result, more enslaved Africans went to the Chesapeake than New England. The New England climate and terrain was not suitable for growing cash crops like tobacco. A plantation economy did not develop in New England because plantation crops would not grow. In the Chesapeake, however, the soil, weather, and flat terrain were excellent for tobacco growing. Had the climate of Virginia been more similar to Connecticut, it’s reasonable to say the two colonies would have been very similar. The sharp contrast in the climates and terrain accounts for much of the difference in the development of the two regions.
Tribes were no longer considered to be independent nations.
