History
The 1000 series were initially built by Tokyu Car Corp. The type was introduced in 1995, and was the first new rolling stock introduced on the Keio Inokashira Line in 33 years, after the 3000 series of 1962. It was the first type on the Inokashira Line to feature 20 m cars with four pairs of doors per side. Third-batch sets from 1711 onward, built from 2003, incorporate system and interior modifications. A new batch of 12 5-car 1000 series sets built by Nippon Sharyo were delivered from fiscal 2008 to replace ageing rolling stock on the Inokashira Line. These new trains feature full-colour LED destination indicators.
Refurbishment
Starting in 2016, the original batch of ten sets is undergoing a programme of refurbishment. Refurbishment includes converting the centre trailer car to a motor car to provide three motored cars per five-car set, as is the case with later-build sets. The ten original sets are all scheduled to be refurbished by 2020.
Livery variations
The cab ends are painted one of several different pastel colours as shown below. The colour is also used for bodyside lining. Set 1729 was repainted in a new "rainbow" colour scheme from 3 October 2012.
