History

Ten four-car sets were introduced from 1961 on inter-running services between the Tobu Isesaki Line and Tokyo Metro Hibiya Line. [1] These were lengthened to six cars per set in 1964 to cope with increased ridership, and ten more six-car sets were delivered between May 1966 and September 1970.[1] The fleet was increased to eight cars per set from May 1972.[1]

Two six-car sets were rebuilt from 2000 series cars in 1988 with new cab fronts for use on the Tobu Noda Line, and reclassified 2080 series. These two sets were withdrawn in 1992.[2]

The last remaining 2000 series sets were withdrawn in 1993.[2]

None of the Tobu 2000 Series cars were preserved.
