If the flow has not been enabled for e-Tickets by the fare setting TOC, then you shouldn't be able to buy it as an e-Ticket anywhere. Trainline often do their own thing though, so might still be an option.
Thanks for the advice. Virgin seems to have done this for all journeys (at least all those I have tried) from the Cambrian for which they set the fare. No point in asking Virgin to change it now, might try when the new franchise-holders take over.
There is every point in asking now, as it will be the same people working for the new franchisee.
I regularly buy tickets from stations and from machines on the Cambrian and am always able to get them with cross London availability.
Good luck persuading TfL to even think about upgrading all their gates in their current financial crisis.
Why? it was the mainline railways who decided to take a system that was working perfectly fine and break it by giving their staff machines that could only print the horrible "bog roll" tickets.
Steam Trains, VHS,Hot Air Balloons, were all working perfectly fine.
And they all still do work perfectly fine! But they were superceded by something better, whereas the card tickets have been replaced by something worse, that doesn't have the same functionality as what went before. The TOCs concerned have replaced the card-ticket machines with something they know are less convenient for passengers, won't operate underground ticket barriers, and means that their staff are now unable to sell tickets to a whole swathe of destinations. Why? Just so that they can use a slightly cheaper printer! I know who I blame for this fiasco.
Stations on the Cambrian mainline all have either a TVM or booking office, which dispense the traditional card tickets. Most stations on the Cambrian Coast don't, and passengers from Coast stations have to buy their ticket from the guard, who now can only sell bog-roll tickets to a restricted range of destinations.
Anywhere that doesn't involve a Cross London journey isn't that restricted for everyday passengers.
I believe it currently also excludes any London Terminal (possibly all terminals) where there is cross availability with a London Underground service.
You believe incorrectly.
Which retailers sell e tickets to London Terminals?
I must be doing something wrong then, Southern and Chiltern both only offered TOD for journeys to London Terminals tonight.
You are confusing retailers with operators
I think to be honest its totally confusing. Southern will offer me an E ticket for internal Southern cross-country journeys to a South Western Station. They will also sell me an e ticket from Harrogate to Leeds (that won't work the barriers at Harrogate). Any ticket to/ from or across London they will only offer TOD. I bought an Advance from Chiltern to Marylebone tonight for tomorrow no E ticket only TOD.
London Bridge has got 14 aisles that have barcode readers. At Kings Cross I think every one of them can. Marylebone has four (I think).
Every LNER gate has a barcode and ITSO reader
brfares.com shows me the fare setters. Where can I see fulfiment methods, please?
No you can't
