Despite being around for many years, GTR's PAYG KeyGo scheme on its Key Smart card has never reached Cambridge (or Peterborough for that matter). It weirdly cuts off at Foxton and Huntingdon (the last stations before Cambridge and Peterborough respectively). It's almost as if they are trying to exclude them. I was wondering why this was, as Cambridge is a major and highly popular station on the GN/TL network. The only reason I can think is that Cambridge is a Greater Anglia managed station (and Peterborough is LNER), therefore the barriers somehow aren't compatible with PAYG - this is exactly why TOCs shouldn't manage stations. However, The Key Smartcard can be used (i.e. pre-paid tickets and flexi seasons etc), so why can't keyGo be used?
