SIR - I’m sorry to disappoint your readers that may be getting excited at the thought of a journey from Leeds to Bradford or vice-versa in 12 minutes. It has been done before in the fabulous, never to beaten, time of two minutes!

This journey was done from Leeds Central station to Bradford Exchange in the early days of the newly-introduced diesel multiple units. A search on YouTube will reveal the recording of this wonderful journey.
