RMS Queen Mary

The RMS Queen Mary was a Cunard ocean liner.

In 1938, a bursar went mad in Cabin 672. There were rumours of the ship being haunted for decades afterwards.

The Fourth Doctor landed on the vessel in October 1963, during a voyage from Southampton to New York City. He discovered that physicist Peter Osbourne had built a time visualiser prototype and was testing it in Cabin 672. It was sending ripples backwards and forwards in time, capturing the fragmentary essences of people in the moments of their worst despair. The Doctor destroyed the machine, but the gestalt of spirits remained bound to the ship, with Osbourne included in their number. (PROSE: Ghost Ship)

Tegan Jovanka reflected that Mawdryn's ship was "more Mary Celeste than Queen Mary", due to the apparent lack of life on board. (TV: Mawdryn Undead)
