The novel plan for the introduction of a rail system in 1832 transformed India, though no action was taken for over a decade. In 1844, private entrepreneurs were allowed to launch rail systems, and by 1845 two companies were formed with support from the East India Company. The first train carried construction material in 1851, and the first passenger service launched in 1853 between Bombay and Thana. By 1880, the rail network reached over 14,500 km, and India began manufacturing locomotives in 1895. Various kingdoms then built independent rail systems that eventually merged into a single Indian Railways unit after independence in 1947.
