Link railcards to oyster

Tip for any occasional visitors to London: railcards can now be linked to oyster cards, reducing the off-peak daily cap from £4.80 to £3.10. I think this is only useful for a small group of people who don’t buy season tickets, but happily I meet all the criteria 🙂 For me it offsets almost exactly the increase in rail fares, which is handy.
