Dear Barry, Query regarding child oyster cards on London Overground services I use London Overground services a lot between Peckham Rye/East Dulwich and central London. I'm so excited about being able to finally use my Oyster card to do this, rather than queuing for tickets in Peckham Rye. My question is about whether or not I need to get my 6 year old his own Oyster card. My assumption was yes, since I have been needing to pay for him to travel on the London Overground train since he was 5. So I went to the Post Office to get an application form for his Oyster card and saw on the notes that it said: "Up to 4 children aged 5 to 10 can travel free on Tube, DLR, London Overground and some National Rail services if accompanied by an adult and do not need a 5-10 Oyster photocard". The Oyster website says the same thing - see http://www.tfl.gov.uk/tickets/faresandtickets/1063.aspx#section-3. I'm confused now about whether or not I need to pay for my son on the overground and whether I need to get him an Oyster. I have always paid before the Oyster system but the official documentation now seems to say I don't need to. I have called the Oyster help line. They were pretty useless and said that I DO need to pay for my son on Overground services but could not explain why the application form and the OYster website says the opposite. Please could you advise. Kind regards.
