Ever took the London tube at Castrate Angel station ? Or Queerer Elastics ? That are some of the names on the London Tube Anagram map, one of the many silly London tube maps on Geofftech.co.uk. But not all maps are humurous by nature : some maps indicate useful stuff for every London commuter : distance and timings between stations, or maps showing dotted walk lines between stations where less than 500 metres, and thus quicker to walk than to take the train between stations.
