Formation

The two eight-car trains, 9008 and 9018, were formed as follows, with six motored ("M") cars and two non-powered trailer ("T") cars.[2]

Designation	M2c	M1	T	M2'	M1'	T	M1	M2c
Numbering	90xx	90xx	90xx	90xx	90xx	90xx	90xx	90xx

The cars of set 9008 were numbered in sequence from 9001 to 9008, and the cars of set 9018 were numbered in sequence from 9011 to 9018.[2] The two M1 cars each had two lozenge-type pantograph, while the M1' car had one.[2]

History

The trains were introduced in 1984, coinciding with the opening of the section of the Hokuso Line between Komuro and Chiba New Town Chūō.[3] The trains were initially classified as "2000 series", and formed as six-car sets.[3] The two six-car train sets were lengthened to eight cars each in 1991, coinciding with the start of inter-running services to and from the Toei Asakusa Line.[3] In 1994, the trains were reclassified 9000 series to avoid confusion with the Keikyu 2000 series trains on the Keikyu Main Line, over which the trains also inter-ran.[3]
