On October 31st, the first 12000 series EMU for the Semboku Rapid Railway was delivered. It is very much derived from the Nankai 12000 series and will be used on limited express through-services between the Nankai Koya Line and the Semboku Rapid Railway Line. The Semboku 12000 series is scheduled to be in service from February 2017, and will probably replace the Nankai 11000 series on the aforementioned through-services.
