The Seibu 30000 series (西武30000系) is a commuter EMU train type operated by Seibu Railway in Japan. It is nicknamed the "Smile Train". A total of 120 4-door vehicles (formed as 18 sets) are on order to be delivered between fiscal 2007 and 2011, replacing older 3-door 101 series and 301 series sets. Three 8-car sets were scheduled to be delivered in January 2008, with subsequent deliveries consisting of nine 8-car sets, three 6-car sets, and three 2-car sets. The trains feature aluminium wide-bodied (2,930 mm) 20 m long cars with no end gangway doors.
The first trains entered service on the Seibu Shinjuku Line in April 2008.
