When delivered, the 800 series sets were painted in the standard Keikyu livery of vermillion red with white window surrounds, but were later repainted into all-over vermillion red with a white bodyside stripe following the introduction of the 2000 series trains.[1]
In November 2016, set 823 was repainted into the original-style livery with white window surrounds.[3]
The 800 series won the 1979 Laurel Prize from the Japan Railfan Club.
The fleet underwent life-extension refurbishment between 1994 and 2001.[1] This involved upgrading the train interiors and also forming six-car sets from the remaining three-car sets by removing the cab ends and adding gangway connections.[1]
Withdrawals commenced in 2011 following the introduction of new six-car N1000 series sets.[1]
The last train, set 823, made its final run as a special charter on 16 June 2019.[4]
The cab end of former car DeHa 812-6 is preserved inside the Maruzen Ikebukuro bookshop in Toshima, Tokyo. Built in November 1979 by Kawasaki Heavy Industries, and originally numbered 812-3, it was renumbered 812-6 in August 1986 following reforming as a six-car unit. It was withdrawn in December 2015, and moved to the ground floor of the Maruzen Ikebukuro bookshop building in March 2017, while still under construction.[5]
