Branded as "NRA" or "New Red Arrow", the trains are used on Koedo services from Seibu-Shinjuku in Tokyo to Hon-Kawagoe. They were formerly also used on Musashi and Chichibu services from Ikebukuro in Tokyo to Hannō and Seibu-Chichibu stations.[1]

edit

As of 1 April 2012, the fleet consists of 12 7-car sets, formed as follows.[2]

History

edit

The first two trains delivered were introduced in December 1993 on Koedo services from Seibu-Shinjuku in Tokyo to Hon-Kawagoe, replacing the former 5000 series Red Arrow trains.[3]

A further three trainsets were delivered in 1994 and introduced on Chichibu services from Ikebukuro in Tokyo to Seibu-Chichibu on 15 October 1994.[3]

The trains were refurbished internally between 2003 and 2008, and the old seats were re-used in Chichibu Railway 6000 series and Izukyu 8000 series trainsets.[4]

On 13 March 2020, the 10000 series trainsets were withdrawn from Ikebukuro Line and Chichibu Line limited express services,[5] being replaced by 001 series Laview trainsets. Since then, the fleet of 10000 series has been used on limited express service on the Seibu Shinjuku Line.[6]

Three cars were transferred to the Toyama Chihō Railway in October 2020. After spending 2021 undergoing preparation, they entered service on 19 February 2022.[7]

Interior

edit

The sets are monoclass with 2+2 abreast reclining seating. Seat pitch is 1,070 mm (42 in).[4]
