This train was also compatible with driverless operation on the Hibiya Line section experimented starting from February 1962 by retrofitting car no.

The first 3000 series trains were built as two-car sets, but the fleet was gradually lengthened to four-car, six-car, and finally eight-car formations, as shown below.

The last sets ran in revenue service on 22 July 1994, with a special "sayonara" run for rail enthusiasts on the following day using set 3055, specially decorated in a "whale" colour scheme and carrying a "Sayonara 3000 series" headboard.

[2] Some trains were sold to the Nagano Electric Railway where they were operated as two-car and three-car sets reclassified as 3500 and 3600 series.

[3] Two cars, 3001 and 3002, were returned to Tokyo Metro's Ayase Depot in 2007 following their withdrawal from service on the Nagano Electric Railway.
