“By the middle of the 19th century, the benefits brought by the host of advances of the industrial age were gradually beginning to reach America, which soon developed a spectacular achievement of its own – the Transcontinental Railway, reaching right across the continent. They battled against hostile terrain, hostile inhabitants, civil war and the Wild West. With two teams, one building from the east and the other from California in the west, they battled against hostile terrain, hostile inhabitants, civil war and the Wild West. Yet in 1869, the two teams’ tracks were joined, shrinking the whole American continent, as the journey from New York to San Francisco was reduced from months to days.”
