History

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]

Interior

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