The painful joy of procrastination and the Tube.

I love my Wikipedia. London Underground Trivia, anyone?

The shortest distance between two stations is 250 metres (0.16 miles), between Leicester Square and Covent Garden on the Piccadilly line. Some say that with all the time spent going up and down the escalators, it's faster to walk between the two. Travel between these stations paid for by a cash ticket costs £25 per mile (£4 ticket) in 2007.

Only two people are known to have had their coffins transported on the Underground: William Gladstone and Dr Barnardo.

A fragrance called "Madeleine" was introduced at St James's Park, Euston and Piccadilly Circus stations on 23 March 2001, in an effort to make the Underground smell better. It was discontinued the next day as it was making people feel sick.

St John's Wood is the only station which contains none of the letters of the word 'mackerel' (as the word Saint is not spelt out). Pimlico is the only station which contains none of the letters of the word 'badger', at least until the proposed 2010 opening of Hoxton, which will then be the only station containing none of the letters of either word. Wapping is the only station with no letters in common with 'lobster'. And Redbridge is the only station without 'Walnut'!

The Jubilee Line is the only line that intersects all others. The District Line meets all other lines except the Metropolitan Line—which it misses by approximately 20 m at Aldgate.

The return journey from King's Cross St Pancras and Euston and back again can be made travelling only in nominally "northbound" trains. The northbound Northern Line runs from King's Cross to Euston and the northbound Victoria Line runs from Euston to King's Cross. It is also possible to make the same round trip on "southbound" trains only.

Note: Oh god the number of times I found myself on the wrong Northern Line. *shakes fist*
