there's one very interesting underground railway in london that the public don't know of is the Post Office Underground Railway (Mail Rail) that run from Paddington to Whitechapel;

It opened in 1927, but closed down recently in 2002 due to making a loss.

Just before closing, the line was carrying 30,000 mailbags per day, with each of the 50 trains taking 26 minutes to cover the seven miles, stopping for a minute at each station. Each train would be loaded with 84 bags of letters and parcels, and would run at speeds of up to 40mph except for in the stations, where the reduced voltage applied to the rails decreased the top speed to 7mph.

(that's the first stock of the Mail Rail)

I thought some of you would like to learn this interesting snibbit, you can see the photo after it closed down here.
