Osaka Metro 30000 series

The Osaka Metro 30000 series is a Japanese city commuter electric multiple unit operated by the Osaka Municipal Transport Bureau and later Osaka Metro since March 2009 on the Midōsuji and Tanimachi Lines. 
==History==
The 30000 series trains were introduced to replace the older 30 series trains operating on the Tanimachi Line which were getting on in age. The trains were largely based on the New 20 series trains with technology developed from the 80 series trains. The first set, 32601, was constructed in November 2008 and used for testing; the trains were introduced on the Tanimachi Line on 18 March 2009 and fully replaced the 30 series trains by 2012.
The trains would later be introduced on the Midōsuji Line in 2011 to replace the older 10 series trains in operation there; the first Midōsuji Line prototype was constructed in June 2011 and tested, with later trains being introduced from 2013 onwards. As of 2020 all 10 series sets have been retired and replaced with 30000 series sets.
From June 2022, some Midōsuji Line 30000 series sets were be refurbished and redeployed on the Chūō Line; these will be reclassified the 30000A series and are intended to replace the older 20 series trains on that line. The sets entered service on 22 July 2022.
==Design==
The 30000 series sets feature a slightly sloped front end with two top-mounted headlights. Later sets feature LED headlights as opposed to projector beams. Numerous interior differences are present with each batch of sets manufactured.
==Specifications==
Construction is of aluminum based on Kawasaki's efACE technology. The sets use IGBT traction systems; early batch sets use Mitsubishi IGBT systems while later sets use Hitachi systems.
==Trivia==
*The 30000 series sets were the last new train type introduced by the Osaka Municipal Transport Bureau for the Osaka Municipal Subway before ownership of the subway system was transferred to Osaka Metro.
*The Midōsuji Line sets and Tanimachi Line sets are often called the 31 and 32 series trains respectively to keep in line with the designations of other trains on the Osaka Metro having two digits; officially however these are designated the 30000 series.
