From Calcutta, the Prince visited Benares (Varanasi), Lucknow, Delhi and Lahore, using the extensive rail networks that had connected many parts of India from the mid-nineteenth century. The railways were developed by the British Indian Government to transport goods and troops. The network was particularly important during the Indian Rebellion (1857), when Lucknow became one of the five cities in northern India embroiled in the conflict, an event commemorated by the Prince during his visit to the city. The Prince himself opened a new railway bridge for the Punjab Northern State Railways in Wazirabad (now in modern-day Pakistan), which crosses over the River Chenab.
