That means switching the car, coupling it to a train.

I'm a gude sleeper, but I'll defy any man tae sleep while his car is being hitched to a train, or whiles it's being shunted around in a railroad yard.

And then, as like as not, ye'll come tae the next place in the middle of the nicht, or early in the morning, whiles you're taking your beauty sleep.

The beauty sleeps I've had interrupted in America by having a switching engine come and push and haul me aboot! 'Is it any wonder I've sae little o' my manly beauty left?
There's a great strain aboot constant travelling, too.

There will aye be accidents.
