The positive result of the British raj’s rule in India was that the country had the fourth-largest railway network in the world by 1900.
The railway that was built in India was because India was a major producer of cotton, they needed the railway to transport the massive number of cotton to British factories so they would produce textiles. The Railway also created markets inside India and increased domestic trade.
The problem was that after the government nationalized the Railways in India the service dropped quality.
