And doing the same with reasonably-priced supplements wouldn't hurt. I had a look in BRFares.com and couldn't see any supplement priced under £120. I used to fairly regularly travel down to London (and parts south) on a day train on the Sunday and get the sleeper back up on Friday night on a supplement. I've changed jobs since so don't have to make those journeys, but if I had to do it now I'd probably just leave early on Friday afternoon.They're already doing this with advances on the classic and club rooms.
