I want to know the answer to the following question:
In the 20th century the Night Ferry was a boat train that provided connections between London and which cities?
All the background I'm provided with is that "Some international railway services to Continental Europe were operated during the 20th century as boat trains, such as the Admiraal de Ruijter to Amsterdam and the Night Ferry to Paris and Brussels.". Is that enough to answer the question?
Answer: yes
