Staying in High Street Kensington tonight and just checked the Oyster fare on TFL and it's £4.90 from Hampton Court (SW Trains) via Wimbledon (District Line). However if I get off and walk from Earls Court (the previous stop) it's only £2.40. Seems a large difference for just for 1 stop? I assume it's because there is a weighting on any travel via Zone 1 as High St Ken is in Zone 1 and Earls Court in Zone 2 I think. Seems a bit harsh when you can travel all the way from Hampton Court (Zone 6) to Earls Court (Zone 2) and then be charged the same again + 10p for 1 extra stop! I know what I'll be doing. Are there any other examples of this?
