Not literally of course but the powers to be at Transport for London have removed it from the latest tube map! However the esteemed Mayor of London has ordered them to put it back on the next print.
People have been making a fuss because the London tube map is a brilliant piece of publicity and of course information. It was first introduced in 1933 and was based on an electrical circuit and is a masterpiece of simplicity.
It is slightly incorrect to call it a tube map however. The term tube only refers to the deep level lines which were built using a boring machine. The rest of the system is known as the Underground and was built on the cut and cover system where a deep trench was dug, the railway was than built and covered over.
