Oyster top up facility - customer update

Passengers travelling on South West Trains services within Greater London have been able to use Transport for London's Oyster pay as you go card since January 2010.
In November 2010, we announced plans to modify our ticket vending machines to allow passengers to also top up their Oyster cards at all of our stations in the London Travel zone from May 2011.
Cubic, TfL's Oyster supplier, is updating its card reader software, which is intended to be deployed on South West Trains ticket machines in Greater London, and this work is taking longer than envisaged. Cubic is TfL's sole preferred supplier and, until this design work is completed, allowing us to liaise with our ticket vending machine supplier to complete the necessary installation, we are unable to offer the top-up facility to our customers.
We would like to apologise to customers who may be inconvenienced by this and we are working very closely with our suppliers to resolve the technical issue as soon as possible.
In the meantime, passengers can check information available within our stations advising them of the nearest location to top up their Oyster card or continue to top up their Oyster cards via the Oyster top up facility on TfL's website.
