All About the London Tube and London Tube Maps and Tickets

From Kathleen Crislip, former About.com Guide

London has a total of 12 tube lines with trains running every few minutes between 5:30-3:30 a.m. Monday through Saturday, and 7:30-11:30 on Sundays, according to the official London Underground. Finding your way to the right tube station and the tube stop you need is remarkably easy, even without your own tube maps.

You'll want a tube map, though -- get free tube maps at any underground station office. You can check out free tube maps online before you go, but you needn't download one to carry across the pond -- tube maps are easy to grab at any train station, and you'll find tube maps posted generously on station walls.
