The Osaka Municipal Subway/Osaka Metro 30000 series (大阪市交通局・大阪メトロ30000系) is a rapid transit electric multiple unit (EMU) train type operated by Osaka Municipal Subway (now Osaka Metro) in Japan since 2009.

Design

[edit]

Thirteen six-car sets were built based on the New 20 series design to replace the older 30 series sets on the Tanimachi Line.[citation needed]

A total of 12 ten-car 30000 series sets are also on order for use on the Midōsuji Line, with the first set entering service on 10 December 2011, replacing the older 10 series sets.[2][3] These 30000 series sets were the final new subway rolling stock to be ordered by the Osaka Municipal Transportation Bureau before it was privatised in 2018.

An improved derivative of the 30000 series, the 30000A series, was first announced by Osaka Metro on 9 December 2021. Changes from the 30000 series include a lower center of gravity, yellow-and-turquoise seat moquette, improved accessibility, and onboard air purifiers.[8] A total of ten 6-car 30000A series sets are due to be built. The fleet began operation in July 2022[9] on Osaka Metro Chūō Line and Kintetsu Keihanna Line through services.[10] Following the 2025 World Expo, the fleet is scheduled to be cascaded to the Tanimachi Line.[11]
