Thanks for the info Mojo, what work would be required at the NR stations?
Slightly on topic / off topic.
I'm thick, how do i get an Oyster card?
Where can I get Oyster?
Adults can order, renew and top up their Oyster card at our Oyster online shop. Customers can also visit a variety of TfL outlets or call the 24-hour Oyster salesline on 0870 849 9999.
* Please note, you can only renew your Travelcard or top up your Oyster card online or by phone if you are able to collect it from a Tube or DLR station. You will need to nominate which Tube or DLR station you want to collect it from.
* Place your order before 2300 and and you can pick it up the following morning. Simply touch your Oyster card on the card reader (not the ticket machines at Tube stations) and your order will be added to your Oyster card.
* You can set up an Auto top-up account online so that whenever the balance for pay as you go on your Oyster card falls below £5, it is topped up automatically. This can only be done at Tube and DLR stations. Auto top-up is not currently available on buses.
