Google is running a doodle on its homepage in India today, celebrating the 160th anniversary of India’s first passenger train journey.

On April 16, 1853, the first passenger train service went between bori Bunder in Mumbai and Thane, covering a distance of 24 kilometers (21 miles), hauled by three locomotives, Sahib, Sindh, and Sultan, according to T. Stanley Babu’s “A shining testimony of progress” (as cited on Wikipedia).

According to the article, “This was soon followed by opening of the first passenger railway line in North India between Allahabad and Kanpur on March 3, 1859.”

On Monday, Google ran a worldwide doodle honoring mathematics pioneer Leonhard Euler.
