one tube minute
I am a huge fan of public transport, especially the London Underground.
Sometimes when the arrivals display shows one minute, it feels longer.
To prove to myself that I'm not nuts I recorded the duration of a tube-minute, on several occasions.
Each dot below represents the arrival of a train on the underground.
The time a dot takes to complete its journey, is equal to the time it took from the
moment the arrivals display switched to one minute until the time the tube doors opened.
