Nankai 50000 series

The 50000 series is used on the Airport Line Rapi:t limited express services. The trains run between Namba and Chiyoda Depot, and have also been used occasionally on special-event services to Wakayamashi and Misakikoen.^{[citation needed]} Between 2022 and 2023, the type was also used on Semboku Liner limited express services on the Semboku Rapid Railway Line.^[1][2]

The external styling of the train was the work of Hiroyuki Wakabayashi, an architect who was also responsible for designing Uji Station on the Keihan Uji Line. The design theme was "Outdated Future", and is the reason for the train's futuristic and retro styling. The end cars feature streamlined cabs without any gangway connections. The cars sport an all-over metallic deep navy blue livery, with the side windows having an elliptical shape, giving the train an aircraft-like appearance.^{[citation needed]}
