Bromley South train station is one of the first in the country to house a new parcel collection and delivery service.
Doddle works from railway stations and major hubs throughout the UK and operates by letting people send and receive parcels from retailers, with notifications through text messages and emails.
After a pilot in Milton Keynes it will be rolled out in Bromley as well as London Waterloo, Cannon Street, Brighton, and Chelmsford.
CEO Tim Robinson says Doddle was created to capitalise on the "booming retail market" and offers a more "convenient delivery solution".
The company has announced 300 stores will open over the next three years, and so far a handful of retailers have got on board.
Network Rail’s managing director, Robin Gisby, said Doddle will mean more profits are invested in the railway.
He added: "More people are travelling by rail than ever before and stations have become more than just a place to wait for, or get off a train.
"Introducing Doddle 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."
