Thanks for posting this vintage 1956 video Captain. I remember, in my teens, seeing the Lord Warden at Dover many times.
Never actually travelled on it but, living in Folkestone, the trip to Boulogne as a passenger was made on The Maid of Orleans many times.
It took me back a few years and I could almost smell and taste the smoking funnels of the steam engines!

Do nothing and nothing happens.
