This idea had been on the cards, if you pardon the pun, since December last year. Now it’s a reality. TFL (Transport For London, or Too Fucking Lame, if you’ve had to deal with the vagaries of the system on a daily basis) have produced a special edition royal wedding Oyster card – yay!

Can one get a carriage to the o2? I hear the Jubilee line doesn't work very well
It will be released a week before the wedding at a cost of £10. £5 for the deposit and £5 minimum credit on the card itself. As you can see, there wasn’t much room for manoeuvre with the design that already exists and the typography is disappointingly dull. We should be grateful they didn’t use Comic Sans – or Zapf Chancery if they wanted to get fancy.
They expect to roll out 750,000 of these cards, which will be sold at every tube station and some overground rail stations. TFL would stand to make between £3.75million and £7.5million if the cards are kept as souvenirs and not returned. Boris Johnson our esteemed Mayor “ Would also recommend the card to the happy couple as the cheapest way of getting around this city, especially as it bears their resemblance.” Now, what are the chances of them using the underground system? Unless, just for laughs, they want to play Russian roulette with their journey, like the rest of us? Would one be topping up one’s Oyster, or would we, the mug public be paying for their high jinks? And if they did pay with their own money, would they be as delighted as Londoners and tourists alike, when they find they’ve been charged double fare because they forgot to touch in as they enter a station without a barrier and/or touch out as they leave?
Just saying.
