India’s first passenger train that chugged out of Bori Bunder in Bombay to Thane 160 years ago was relived by Internet search engine giant Google on its homepage on Tuesday.

In the doodle, the locomotive train replaces the first ’O’ of the word Google.

The idea of a railway to connect Bombay with Thane, Kalyan and with the Thal and Bhore Ghats first struck George Clark, the then chief engineer of the Bombay government, during a visit to Bhandup in 1843.

The first railway ran over a stretch of 21 miles from Bombay to Thane. The formal inauguration ceremony on April 16, 1853 saw 14 railway carriages, carrying about 400 guests; leave Bori Bunder at 3.30 pm amid loud applause and to the salute of 21 guns.

Doodles are the fun, surprising, and sometimes spontaneous changes that are made to the Google logo to celebrate holidays, anniversaries, and the lives of famous artists, pioneers, and scientists.

On February 8, the Google doodle commemorative logo paid tribute to Ghazal king Jagjit Singh on his 72nd birthday. On the occasion of 64th Republic Day, Google doodled a Royal Bengal tiger on its India homepage.

A group of Googlers get together regularly to brainstorm and decide which events will be celebrated with a doodle. The ideas for the doodles come from numerous sources including Google users.

The doodle selection process aims to celebrate interesting events and anniversaries that reflect Google’s personality and love for innovation.
