Interactive History of Moscow Metro
Moscow metro works since 1935. This map contains a slider which allows you to follow the history of Moscow metro, to see how it was built and how it is expanding along with changing names of the stations.
Note that several stations appear to be closed during some periods of time. Either these stations did not exist at that time or metro trains passed them without making stops.
Line colouring is standard for maps used in Moscow today, but in the very beginning there were no colour division. Some stations did belong to different lines in the past. Several stations have similar names but belong to different lines, several of them even have no direct connections.
