Now if viewers of a current TV cyber disaster thriller were wondering the actual Caledonia sleeper is rail luxury without the drama.
Train enthusiasts including Herself, who used to spot locomotives as a kid with her Dad have been glued to BBC pulse-pulping series Nightsleeper.
Which follows an unfortunate group of passengers from Glasgow to London whose train has been hackjacked.
Rolling stock
And is being operated remotely by terrorists.
No jokes here about British train operators please.
Because the real sleeper from London to Scotland is a calm, stress-free breeze through rolling hills and valleys.
Before you arrive refreshed, refuelled and ready for your day in Edinburgh.
With, of course, as is always the case in the Scottish capital, five minutes to spare.
Time of your life

To give passengers extra insurance when running for their train.
As I found out on one of my early travel assignments when invited to let the train take the strain from London Euston.
Being used then to taking Stagecoach bus overnighters.
Where you got a carton of juice and small snack and a half-hour break to stretch your legs around Yorkshire the Caledonia Sleeper was a definite upgrade.
Bed & Breakfast
Now that was 35 years ago so I fully expected the landscape to have changed particularly as I’d got used to flying.
So £400 for two guests in an en-suite made me gasp as much as Joe Cole’s ham acting in Nightsleeper.
But after I caught my breath I got to thinking that you’re cutting out accommodation here too.
Caledonian Sleeper offers twin bunk beds and en-suite shower room.
And priority access to the Club Car and station lounge access with breakfast included onboard.
Your sleeper leaves London Euston at 11.45pm and gets you into Edinburgh Waverley at 7.30pm in one piece.
Sleep it off
There are also London to Glasgow and to Aberdeen sleepers.
Dearer, granted, than the overnight coach that took me from the frozen north to The Big Smoke.
To meet a golden Aussie beauty I had befriended at the Munich Beerfest.
Only for her to stand me up before bumping into her later that night at the Oktoberfest reunion… with her Scottish boyfriend.
I could well have done with a soft pillow to cry myself to sleep on my trip back that night rather than a hairy itinerant worker.
And which I found out a couple of years later that the Caledonia sleeper is rail luxury without the drama.
