Didn't there used to be trains that instead of disgorging their
passengers at the docks actually drove (drove?) steamed on to sidings
on the decks of ships then steamed off Stena-like to continue their
journey across Europe?

Yes you are correct. In 1990 I was on a train from Denmark to Sweden and
instead of getting of the train to board the boat, they simply loaded the
carriages onto the train, there were rails imbedded into the deck

It took a while to chain the carriages down and it was a bit disconcerting
to be sitting in a railway carriage that was going up and down as opposed to
rocking from side to side. 1 person in my compartment didn't even realise we
were on a boat, it was night time, and went to use the toilet, before the
days of retention tanks.

It was a very smooth operation and a very strange experience
