History

The prototype set, 10-010, was built in 1971, and initially tested on the Toei Mita Line.^[3][4]

Refurbishment commenced in fiscal 2009. This consisted of adding external speakers, replacing the original roller blind destination indicators with LED indicators, moving the body side destination indicators from the ends to a central position, and adding interior passenger information displays.^[2]

10-300R series set 10-340, formed of former 10-000 series intermediate cars, May 2006

In 2005 and 2006, the 10-xx7 and 10-xx8 cars of sets 10-010 to 10-180 were refurbished and reformed with new driving cars to become 10-300R series. These cars were built between 1986 and 1989 as batches 3 and 5 to lengthen original 6-car sets to 8 cars, and so were still relatively new compared to the rest of the cars in the sets in which they were contained.^[5]

The final set, 10-280, was retired on 11 February 2018.^[6]
