It's safe to say Transport for London (TfL) is pushing hard to equip London's bus and train networks with their fair share of tech. Not long after it announced the launch date for contactless payments on the Tube, it's just confirmed that two of the city's Routemasters are now offering free WiFi to passengers. As of today, if you find yourself travelling on a specific route 12 bus, which operates between Dulwich and Oxford Circus, or a route RV1 bus journeying between Covent Garden and Tower Hill, you'll be able to get online without eating into your data allowance.
