Do all the TVMs, or at least all the LNER TVMs, at King's Cross, Doncaster, York and Edinburgh offer this facility, or only certain ones? If it's only certain ones, is there any way of identifying which ones they are, or do you only find out once you've touched the screen?
Do they offer all rover and ranger tickets for everywhere in the country whether they are valid on LNER or not (and whether they are valid from the station in question or not)? And can you buy them in advance of the day of travel or only on the day of travel? If the latter, do you know if LNER plans to make them available in advance at a later date, just as I understand that Northern plans to at some point?
