Background JR East introduced the
209 series in 1993, initially on the
Keihin–Tōhoku Line and
Negishi Line, to replace the
103 series trains that were previously used. 209 series sets were later deployed on other lines, including the
Nambu and
Kawagoe lines. Designed to be a low-cost, lightweight, minimal-lifespan vehicle, the 209 series design set the standard for subsequent JR East commuter train designs.
Inheritance by Izukyu Corporation In July 2021, Izukyu Corporation announced its plan to procure 209 series trains that were previously operated by JR East on services throughout the Bōsō Peninsula. The following month, Izukyu announced that the fleet would be given the classification "3000 series". The 3000 series incorporates a Hawaii-inspired theme; this is reflected through the brand name "Aloha Train", a
Honu-inspired external wrapping pattern, a color scheme borrowed from the "Resort 21" trainsets, and internal door wrappings of various seas in Izu. They are also the first trains operated by Izukyu to use
variable-frequency drive (VVVF) technology and also did not require large-scale refurbishment. In contrast, the older
8000 series trains inherited from
Tokyu Corporation required the installation of toilets, onboard passenger information displays, electrical coupling, and transverse seating; these features were already included with the 3000 series sets upon their inheritance by Izukyu Corporation. Originally, the fleet was only used on the
Izu Kyuko Line, but on 13 June 2022, they began use on the JR
Ito Line as well. == References ==
