Design

The 3000 series was the first Keio rolling stock to use completely stainless steel body construction.[1] A total of 29 5-car sets (145 cars) were built from 1962 by Tokyu Car, and in 1963, the design was the recipient of the third Laurel Prize presented annually by the Japan Railfan Club.[2]

Each trainset featured a livery in one of the seven pastel hues corresponding to a train configuration, a unique feature found only on the Inokashira line. A number of trains were later resold to operate on other lines throughout Japan.

History

The first trains entered service on the Inokashira Line in 1962.[1] The fleet underwent refurbishment from 1996, with the original fibre-reinforced plastic (FRP) cab ends replaced by new steel cab ends with panoramic windscreens and front skirts.[1]

Withdrawal and resale

Withdrawal of the 3000 series fleet began in 1996 following the introduction of new 1000 series sets. The last remaining sets were withdrawn by the end of 2011.[1] The withdrawal dates for the later, refurbished sets were as shown below.[4]

A number of sets were resold to other private railway companies, including the Hokuriku Railroad, Jomo Electric Railway, Gakunan Railway, Matsumoto Electric Railway (Alpico Kotsu), and Iyo Railway. In 2007, it was announced that former 3000 series EMUs would be resold to the Choshi Electric Railway in Choshi, Chiba, and converted to two-car sets. However, this plan was cancelled due to the cost of converting the 1,500 V DC cars to 600 V DC operation.[6]

Hokuriku Railroad

Two early, narrow-body 3000 series sets were resold to the Hokuriku Railroad in Kanazawa, Ishikawa, where they became two-car 8800 series sets 8801 to 8802.[7] Later, wide-body sets were also resold to become two-car 7700 series set 7701 and 8900 series sets 8901 to 8903.[7]
