“When Britannia was used for royal honeymoons, the crew (known as Yachties) would rope two single beds together,” writer Brian Hoey revealed in his book ‘Not in Front of the Corgis.

As for the Royal Train, it also features a “rather grand banqueting table” which seats 12, Myers added.

Prince Philip has his own saloon carriage of similar design to that of the Queen with a kitchen, green curtains, matching chair cushions and a brown carpet.

Prince Charles, 72, also has his own lounge car complete with a bedroom, bathroom and study with a small writing desk, and a blue-and-white floral patterned sofa with matching curtains.
