The scheme’s introduction has been delayed by a year as transport chiefs said they did not want to risk teething troubles in the run-up to the Olympics. The technological challenge of installing it on the Tube — working with banks and Redhill-based TfL contractor Cubic — is much greater than on the buses.
Caroline Pidgeon, leader of the Lib-Dem London Assembly Group, said: “It is time the Mayor gave some clear answers on how wave and pay technology will finally be rolled out across the Tube, DLR, trams and Overground.
“He needs to clarify his long-term vision for Oyster and ensure its fares always stay the cheapest available.”
TfL’s director of customer experience Shashi Verma said: “Ahead of the introduction of contactless payment card acceptance on the Tube, London Overground, trams and DLR next year we’ll conduct a controlled pilot involving staff, stakeholders and other interested groups. We are finalising the plans and more details will be available soon.”
