The Seibu 4000 series (西武4000系) is an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway mainly on Seibu Chichibu Line services in Saitama Prefecture, Japan since 1988.[1]
Design
The 4000 series trains were built between 1988 and 1992 by combining electrical equipment from former 101 series EMUs with new steel bodies.[1] The trains are finished in a livery of ivory white with blue, red, and green stripes along the waist line, the team colours of the Saitama Seibu Lions baseball team.[1] The driving cabs have a similar configuration to the earlier 101 series and 2000 series EMUs, with a left-hand master controller and right-hand brake control.[1]

Operations
The fleet of four-car trains is primarily used on local driver only operation services on the Seibu Chichibu Line between Hannō and Seibu Chichibu, but the trains are also used as eight-car formations on through "Rapid Express" train services from Ikebukuro on the Seibu Ikebukuro Line to Mitsumineguchi and Nagatoro on the Chichibu Main Line.[1] These trains divide and couple at Yokoze, with separate portions for Mitsumineguchi and Nagatoro.[1]
Fleet
As of 1 April 2013, the fleet consists of twelve four-car sets, numbered 4001 to 4023, based at Musashigaoka depot.[2]
