History

The first trains were delivered in December 1987, entering revenue service from 22 March 1988.[6] From 2007, the train type was displaced from Tokyo Metro Chiyoda Line services by new 4000 series 10-car sets. Since then, they have been used on surface-level Odakyu Line services, as well as some portions of the Hakone Tozan Line.[7]

Refurbishment

Refurbished 10-car set 1096 in August 2020

From 2014, 160 out of the operational fleet of 196 1000 series started undergoing a programme of life-extension refurbishment.[8] The refurbishment includes the replacement of the existing traction motors with new 190 kW AC traction motors, silicon carbide inverter traction control, and new air-conditioning units with 8% higher capacity.[8] The interiors were completely refurbished with LED lighting, LCD passenger information displays above the doorways, and new moquette seat covers.[8] The exteriors also received LED headlights and direction indicators.

As of August 2022, two unrefirbushed trainsets remain in operation: a 6-car set and a 4-car set.[9]
