I took the train up to East Croydon as I had an appointment to view a takeaway which is for sale in Biggin Hill.
From the station caught a tram to New Addington which was a first time experience. No tickets, no cash transactions. Instead there are card readers at the tram stops which accept contactless cards.
I still had an Oyster card from when I arrived two years ago and waved it uncertainly at the reader.
I am still not certain how it works and whether it did deduct what it should have done. The reader asks one to tap in to validate. If you get confused, as I did, and tap it again, it suggests you seek help.
Who from I am not sure.
I just climbed on the next tram to see what happens next. Apparently journeys are one pound fifty on a designated route irrespective of where you get on or off.
But as I understand it you are supposed to tap in and out and I suspect I am missing something. But as long as you are clutching a card that works I am sure someone will eventually appear to check who is paying and who is not and they will explain.
