India's railroad history began in 1837 when The Red Hill Railway used the country's first steam-powered locomotive to carry stone for road work to Madras, modern-day Chennai. In 1845, India's first railway was incorporated, the Madras Railway. Sixteen years later, on a warm April day in 1853, a 14-carriage train carrying 400 passengers was hauled 21 miles by three steam locomotives - the Sahib, Sindh, and Sultan - and passenger railway service was thus initiated in India. From there, as they say, the rest is history, and India today has the world's fourth-largest railway network.
