The Oyster card scheme has been rolled out at two stations.

Oyster and Pay-as-you-go (PAYG) technology is now available at Radlett and Potters Bar stations following a successful campaign by Hertsmere MP Oliver Dowden.

The new scheme means passengers will be able to tap in and out easily and save money.

Mr Dowden was joined by Transport Secretary Grant Shapps at Radlett station on Thursday morning to officially mark the arrival of Oyster and contactless cards.

For passengers who travel irregularly or prefer to ‘turn up and go’, Oyster and PAYG will be the most convenient and cheapest option to travel. Passengers who purchase a Radlett to London Underground Zones 1-2 return ticket for instance will save £4.80 by using their Oyster or contactless card instead.

Mr Dowden said delivering Oyster to Radlett and Potters Bar was one of his "key priorities" since he was elected in 2015.

He has met regularly with rail ministers and the transport secretary over the last three years and lobbied for the funding.

Mr Dowden said: "I’m delighted that after years of campaigning, we finally have contactless pay as you go travel in Radlett and Potters Bar. I know this will make life easier for commuters and particularly people who travel irregular hours, which more and more people are doing with the increase of part-time working and working from home."

David Gornall, commercial director at Govia Thameslink Railway, added: "We have worked closely with Transport for London and the Department for Transport to realise this ambition and look forward to further expansion of pay as you go later this year."
