A new online shopping collection point chain founded by Network Rail and the owner of Travelex is to open one of its first branches at Waterloo Station.
Doddle says it will open in 300 new locations in the next three years, creating 3,000 jobs.
Retailers already signed up to use the service include ASOS, TM Lewin and New Look.
In addition to the pilot store in Milton Keynes station, the first Doddle shops to be opened will include London Waterloo, Bromley South, Brighton, Chelmsford and London Cannon Street.
Doddle branches will be open seven days a week early until late.
Doddle is an independent, standalone limited company, with Network Rail and Lloyd Dorfman holding equal shareholdings.
Lloyd Dorfman, who will serve as Doddle chairman, is best known for founding the world's largest retail foreign exchange business, Travelex.
He said: "I signed the Doddle joint venture contract literally hours after signing the recent Travelex deal. We intend to take the experience of creating a challenger brand to provide a game-changing service for millions of online shoppers."
Tim Robinson, chief executive of Doddle and a former Network Rail manager, said: "We created Doddle to improve the online shopping experience.
"We're not another 'me too' click and collect offer, it's a game-changing service consumers are crying out for but no one else can provide.
"We offer a premium service with contemporary shops, advanced technology and highly trained staff delivering a dedicated customer experience. It is the next major step in online shopping, providing a parcel collection, returns and delivery service that has customer choice and convenience at its very heart. What's more, we are delivery carrier and retailer agnostic so any brand can offer the Doddle service to their customers."
Robin Gisby, Network Rail's managing director for network operations, said: "Introducing Doddle to stations will enable us to reinvest our profits back into the railway and is a natural next step to help passengers and people who work and live near stations, whose lives are increasingly busy and on the move."
