This is a good point - equally though, I'd hope the people on the forum can see what's a sleeper issue (staff / haulage / coaches / etc) and that there haven't been many of these reports for a while (seated car excepted!). The *lack* of sleeper-specific faults is what made me happy enough to book the Monday night sleeper instead of an early flight on Tuesday though I'd have preferred a spot on the Glasgow lowlander (or Edinburgh at a push) instead of having to join the Fort William portion at Dalmuir. It's been a few years since I used the sleeper, so I was interested to see if there was any of the "running down" in the run up to new stock introduction that some people have suggested.
I didn't see it. The coaches are tired but everything worked. Yeah, we were delayed in Lancashire and that pushed us onto the slows as we neared London resulting in a 49L arrival, but I booked it knowing that even if there was a small delay, it would be better than getting up at 4.45 to fly down. It still had me in Docklands earlier than flying to Heathrow, Gatwick, Luton or Stansted (i.e. unless I wanted to spend over £500 on a return from Glasgow to City).
I'm more annoyed at Dalmuir's waiting room closing at midnight, instead of waiting for the Fort William section to come through, than any delay, but waiting room closure times are a ScotRail issue rather than sleeper again.
And then, what I lost on arrival time, I mostly made up by going HS1 to Stratford Int'l instead of the tube - not a cheap way to travel 6 miles, but averaging 60mph it is fast!
Not sure if or when I'll need to make that journey again, but I'd certainly go by sleeper again. I might book a little earlier next time though... It wasn't cheap and the fact that I can't book through third party sites any more (combining with day train) really annoyed me at the time of booking, but the move to 2x singles per return (instead of one return ticket) clearly means they have less exposure to a 2hr delay in one direction resulting in both directions being fully refunded.
