Nankai 8300 series

The Nankai 8300 series is an electric multiple unit commuter train type operated by the private railway operator Nankai Electric Railway in Japan since 8 October 2015.
The similar Semboku 9300 series runs on the Semboku Line and Nankai Koya Line in Japan since 8 August 2023. Two 4-car sets were built by Kinki Sharyo in 2022.

Operations

The 8300 series trains are used on Nankai Main Line, Nankai Wakayamakō Line, and Nankai Airport Line commuter services singly or coupled with 12000 series EMUs on Southern Premium limited express services to provide non-reserved accommodation.
Since 22 November 2019, 8300 series trains have been used on Koya Line services. Nankai expects to deploy additional 8300 series trains and replace the entirety of the 6000 series fleet on the Koya Line by 2023.
The 9300 trainsets are intended for service between Namba and Izumi-Chūō stations on the Semboku Line, as well as through services onto the Nankai Koya Line.
