The Nankai 6000 series (南海6000系) is an electric multiple unit (EMU) train type operated by the private railway operator Nankai Electric Railway in Japan since 1962.

The 6000 series is used mainly on Nankai Koya Line commuter services.

Since these are older cars, they lack many features found in modern sets such as LCD screens and light-up maps.

It is generally rare for any rail car to last beyond 50 years in service.

[3] Two-car set 6905 was transferred to the Ōigawa Railway in July 2020.
