Nankai 50000 series

The Nankai 50000 series is a Japanese limited express electric multiple unit operated by the Nankai Electric Railway since September 1994.
==History==
The 50000 series sets were introduced on 4 September 1994 to coincide with the opening of the Kansai International Airport. A total of six sets were produced, all by Tokyu Car Corporation (now J-TREC). The sets are the recipient of the 1995 Blue Ribbon Award. Refurbishment occured from 2015 to 2018, replacing underfloor equipment and other changes.
==Design==
The 50000 series sets use a unique design, sporting a deep navy blue livery and a futuristic streamlined design. The design was penned by Hiroyuki Wakabayashi with an "outdated future" motif, with development carried out jointly between Tokyu Car and Nankai. The cars feature circular side windows to combine the image of trains and airplanes as well as to emphasize the train's use as an airport limited express train.
==Specifications==
Construction is of steel. The trains use later-specification GTO drives manufactured by Hitachi which produce a wailing sound. During refurbishment these were replaced with IGBT drives produced by Mitsubishi which produce a high-pitched wail.
The trains feature an electronic horn which produces a low, bassy tone reminiscent of a French horn or similar instrument.
