There's a Map That's Been Constantly Updated for 200 Years - Apparently.
The Times 1000, a detailed map of the world's railways, has been published annually by The Times newspaper in London since 1824. Each edition is a cumulative update of the previous year's map, with new lines and stations added, and old ones removed. The current edition is a staggering 4 meters long and weighs over 1 ton, making it one of the largest and most detailed maps in existence.
