The Moscow Metro declared that it has reached the record short 80-second headway on the Circle Line (Line 5) during the tests of the train operation control system.
The result became possible after the modernization of the control system on the line, which took place in early 2023. During the tests, up to 45 trains were running on both tracks, so they arrived at the stations with a minimum headway of about 80 seconds – faster than in Paris, Tokyo, Hong Kong, and Beijing subways.
