Trainline is the tech provider for East Midlands Railways’ trial of Digital Pay As You Go. There are three more trials in England on the Northern railway each with a different tech provider (not Trainline). As I understand it how DPAYG works it requires a smartphone, app and crucially the downloading of a barcode to be scanned at a barrier at the start of a journey. The end of the journey will be determined by geolocation on the smartphone or presumably scanning at a barrier (if there is one) at the destination station. At the moment it is therefore (because of the use of a barcode) seemingly not that different from having a digital ticket. The crucial difference seems to me that you do not appear to pay in advance but in arrears - I would guess by payment being taken automatically from your account using preloaded payment details given to the train operator. A major benefit to the customer of paying in arrears is that the system will automatically give them the best price based on their rail journey activity in a particular day or perhaps week.
I think the barcode is necessary because for revenue protection the train operator needs its revenue protection teams and guards to have some way of checking where someone has started their journey.
It seems to me that, for the moment, three different digital models may emerge. Firstly, just paying by bank/credit card (I think this is still how the Tube still works but haven’t used it for quite a while). This works for short journeys costing not too much in a largely enclosed rail network with barriers at nearly all stations so evasion is minimised. Secondly, at the other end of the spectrum will be digital rail tickets for long journeys where there is significant incentive to fare evade much more significant journey costs and so revenue has to be protected by tickets and barriers. Somewhere in between is the EMR type hybrid model where most journeys will be short but a passenger can get access to a rail network that can take them long distances ie the network is not as enclosed as eg the Tube.
It is all rather complex and there are issues around collecting failed payments, family groups being catered for, refunds for cancellations, delays etc. The structure and tech cannot be easy and it will need the expertise of a company like Trainline.
There is actually an article in The Times today about revenue protection at Waterloo and the problem of short ticketing. Fare evasion is reckoned to lose the entire rail network around £350m - £400m a year. So not trivial.
