The Semboku Liner () is a limited express train service operated by the private railway operator Nankai Electric Railway between Izumi-Chà «à  and Namba stations in Osaka Prefecture, Japan.
The Semboku Liner operates over the Nankai Kà Âya and Semboku lines between Izumi-Chà «à  and Namba stations, with intermediate stops at Kà Âmyà Âike, Toga-Mikita, Izumigaoka, Tengachaya, and Shin-Imamiya. The journey takes approximately 29 minutes. 12 inbound services and 11 outbound services are operated on weekdays, and 12 return trips are operated on weekends and holidays.
The Semboku Liner made its operational debut on 5 December 2015, coinciding with a revised timetable for the Nankai KÃ Âya Line and the Semboku Rapid Railway Line. Originally, 7 inbound services and 6 outbound services were operated on weekdays, and 8 return services were operated on weekends and holidays. Additional workings were added with the start of the 26 August 2017 timetable revision.
The Semboku Liner is normally operated using Nankai 11000 series and Semboku 12000 series sets. The Nankai 11000 series, originally developed for use on Rinkan limited express services, was the first train type used on the Semboku Liner. A dedicated Semboku 12000 series trainset was introduced on 27 January 2017.
