It's probably worth noting at this juncture that, at my local station, which is TfL-operated and therefore only accepts CCSTs, as well has having both ticket machines and a ticket office, the majority of people who don't have season tickets still buy mobile tickets from Trainline and show them to the person on the barrier. So I wonder how low use of physical paper tickets is in places where e-tickets do work ticket barriers (if any)?
That being said, I do think that moving to these new varieties of paper ticket is a huge backwards step. CCSTs not only look smart, but they fit in a wallet (it's in the name, after all!) and are relatively robust. Printing out journey details on a flimsy strip of till roll and calling it a ticket is emblematic of the total PR disaster the railways have been lurching through for some time: is it a crisp, well-branded, piece of firm card, or a glorified Tesco receipt that languishes, forgotten, in the bottom of your pocket?
OK, I may be overreacting just a little bit

- but my point is that people who don't like the growing proliferation of e-tickets and new paper tickets are not merely hankering after the past, nostalgic for magstripes, chronically unable to move with the times etc. etc. Should we get over it? Probably, but CCSTs will have to be physically prised from my fingers when they do go!
