About the Project
Transport for London (TfL) has awarded Indra a long-term contract to operate, develop, enhance and expand ticketing and access control systems across London’s transport network through to 2034, with extension options to 2039.
This programme covers the maintenance, operation and evolution of a large-scale, complex ecosystem, including turnstiles, validators, ticket machines, sales terminals, back-office systems, payment gateways, IT infrastructure and cybersecurity that supports over 8.6 million daily journeys.
Therefore, Indra will become TfL’s strategic technology partner to guarantee the operation and evolution of the world’s largest and most sophisticated ticketing system. Following a transition period of approximately two years, Indra will serve as the sole provider across the network that includes more than 8,500 buses, nearly 400 Underground stations, around 300 rail stations (Overground, DLR, Elizabeth Line and suburban services), 4,000 Oyster Card outlets, seven customer service centres, and 24 river boat boarding points.
Drawing on over 30 years of experience in urban public transport solutions, Indra will manage and evolve all aspects of the system. The project also envisages, in partnership with TfL, the implementation of new technologies to develop the system, make it more efficient and automate key processes; in short, to jointly create the next generation of the ticketing system for London.
