The 3000 series was created by modernizing old Tobu EMU cars dating from the 1920s and 1930s, by adding new 18 m long steel bodies based on the 2000 series design, with three pairs of sliding doors per side, and front ends based on the 8000 series design. The fleet was subdivided into 3000, 3050, and 3070 series types.[1]

3000 series

The 3000 series sets were rebuilt between 1964 and 1971 from 134 former 3200 series EMU cars, originally formed as 30 four-car and seven two-car units. Eight of the four-car sets were subsequently reformed as six-car sets by adding two intermediate cars from other four-car sets.[1] All sets were based at Nanakodai Depot and used on Tobu Noda Line services.[1]

The 3000 series fleet was withdrawn by 1992.[2]

3050 series

Following on from the earlier 3000 series sets, a total of 68 former 5400 series cars were rebuilt between March 1971 and December 1973, formed as ten four-car sets and 14 two-car sets.[1]

The 3050 series fleet was withdrawn by 1996.[2]

Formations

The 3050 series were formed as follows.[1]

4-car 3050 series

Designation McTc
Numbering 35503650

3070 series

The 3070 series sets were built between January 1974 and May 1975 by modernizing 34 former 5310 series, 5320 series, and 5800 series EMU cars dating from the 1930s with modern new steel bodies.[1] The 3070 series fleet was formed as six four-car sets and five two-car sets.[1] They were originally numbered in the 5xxx series, but renumbered in the 3x7x series following the appearance of the 5000 series in April 1979.[1] This renumbering unified all of the 18 m EMUs into the same 3000 series, but the 3070 series sets were not able to run in multiple with either 3000 series or 3050 series sets.[1]

All of the 3070 series sets were based at Tochigi Depot for use on the Tobu Nikko Line, Tobu Utsunomiya Line, and Tobu Kinugawa Line.[1]

The 3070 series fleet was withdrawn by 1996.[2]
