The lowland sleeper London-Glasgow/Edinburgh isn’t long enough for a good nights sleep in my view.

Yeah, you can stay on it for a bit longer after they arrive but you'd have to be very asleep not to notice the lack of movement and noise of the station around you. Funny enough the best night I had on it, it was delayed by a few hours (normally a horrible thing on the train but perfect on a slightly too short sleeper!).

That’s exactly what I mean. I never sleep much better than I would sleeping in a car.

I suppose it’s the novelty of sleeping in a moving vehicle, my flight attendant friend said it took them a while to start sleeping well on long haul flights.

Perhaps with a lot of benzodiazepines or drowsy anti-histamines I could attempt to sleep well in a sleeper train, but not normally. Happy for those who can of course.

Gotcha. It's the same for me on an airplane (I think maybe because I'm unable to fall asleep on my back), but I didn't have problems on the sleeper train.

Do you think it's the noise for you, the movement, or something else (like lack of privacy)? I started taking earplugs with me for any kind of trip now, they are a godsend.
