According to the official website of Hankyu Electric Railway, semi-express trains(準急) on Hankyu Kyoto Line will run through into Sakaisuji Line(堺筋線) every 20 minutes during the daytime of every Saturdays and Sundays.
The reason of it is said that Hankyu would like to get passengers from Kansai International Airport(関西国際空港), where we can go directly from Tengachaya station(天下茶屋駅), which is the terminus of Sakaisuji Line.
Especially, it seems that Hankyu would like to get foreign passengers. This is because the extra train whose announcement in the train will be taken place in English, Chinese, and Korean is to run.
With the decrease of inhabitants in Kansai, railway companies such as Hankyu are forced to manage in bad shape.
So, they intend to find out the demand in tourists from foreign countries.
