April 16, 2019, marks the 166th anniversary of India's first passenger train journey in which 400 invited passengers traveled in 14 carriages on a 57-minute journey from Bori Bunder in Bombay (now Mumbai) to Thane. Since that first journey in 1853, railways have become one of the most important modes of transportation in the country. Here's a look back at the early days of Indian railways in a series of photographs from the 19th century.
