An update from @lner. If a trains reservation display system goes offline. You have no right whatsoever to your booked seat if someone else is sitting in it. You can simply ask for a refund.
@LNER So I gather that if there's a system fault it invalidates everyone's booking. I guess the public don't know this. Including the train manager of the 0755 from ncl who turfed some out of a seat while the system was down. I'm clearly wasting my breath and raise a formal complaint
@lner ref uk 2000 transport act. Why aren't open ticket holders being removed from reserved seats?. Why aren't @lner enforcing the bylaw and train managers getting people out of reserved seats they don't have a reservation for?
@LNER You need to contact the train manager and ask him to make an announcement to the train which says "get out of the seat you are occupying if there is someone showing you a valid booking" some people on route to Edinburgh have been standing since KC even though they have a booking
@LNER It's very upsetting when you've customers fighting over a booked seat and #lner staff not support the Customer with a valid booking on their phone
