The first underground electrically-operated railway made its debut 150 years ago today in London. To mark the occasion for seachers in the UK, Google has posted a Doodle on its homepage featuring its letters atop the famous map of the London Underground.
The color-coded Tube map can be traced back to electrical engineer Harry Beck. His original map design became the blueprint for modern transportation systems.
The Transport for London website is embracing social media, enticing website visitors to follow them on Twitter and Like their Facebook page to discover key milestones from the history of the Tube and learn 150 facts via Facebook in honor of the milestone.
Google Maps added public transport directions for the London Underground in July 2011.
