India was the jewel in the crown of the British Empire. There were vast riches to be exploited and vast numbers of people to be subjugated. How better to achieve these aims than by building a rail network that facilitated the export of raw material and made it easier for troops to travel around the country to tackle uprisings? India joined the railway age late: the first line was not completed until 1853, but, by 1929, 41,000 miles of track served the country.

The opening of the pioneering Liverpool & Manchester Railway in 1830 marked the beginning of the railway network's vital role in changing the face of Britain.

Powers and Thrones takes listeners on a journey through an emerging Europe, the great capitals of late Antiquity, as well as the influential cities of the Islamic West.

The Pennsylvania and the New York Central railroads helped to develop central Pennsylvania as the largest source of bituminous coal for the nation. By the late 19th century, the two lines were among America’s largest businesses and would soon become legendary archrivals. The Pennsylvania Railroad (PRR) first arrived in the 1860s. Within a few years, it was sourcing as much as four million tons of coal annually from Centre County and the Moshannon Valley and would continue do so for another quarter century.
