Monthly Rail Travelcards

Living in Romford doesn't only mean they've got orange girls and hair-straightener-straight-hair boys for shop assistants, it also means I'm taking the train into London. Yes, ladies and gents, I'm actually outside the tube net!

Someone figure that for me tho: It's still zone 6 and part of London transport. But I can't use my oyster card because it's a railway station without a reader. I need to buy a paper ticket for which, if I want a monthly one, I need to get a photocard from. That photocard I can only get issued at tube stations.

YOU WHAT???
