Phil, I presume the loss of sleeping accommodation means rail travel has become less viable. Sorry to hear if that's the case. I travelled on the Sunlander more years ago than I care to admit, and I 'm disappointed about the so-called 'rail-bed' replacements.
It reminds me of open plan offices where there is no privacy, no chance to think, just lumped in with everyone.
Anyway, am happy to help out with a pic if you're ok with that.... after some time off earlier this year, I now have a few more recents to play with.
Anyone care to guess where this is?
