Keisei AE100 series

The Keisei AE100 series (Airport Express) is a limited express electric multiple unit operated by the Keisei Electric Railway from June 1990 to February 2016.
==History==
The AE100 series sets were introduced as a new and modern train to ply the Keisei Main Line. Initially intended to aid with the increasing number of passengers on the line, two sets were manufactured to complement the AE series sets also operating the Skyliner services on the line in preparation for the line's entrance into the a new terminal building of the Narita International Airport. The sets would then ultimately be used to replace the older AE series sets, with five more sets built; all AE series sets were replaced by 1993.
These were a mainstay on the Skyliner service until the introduction of the second generation AE series sets in 2010, when the Skyliner logos on their bodies were removed. The sets were then relegated to mostly Cityliner services until those were discontinued in 2015, at which point the sets were removed from regular service. The sets saw some temporary special operations in early 2016 before a decision was made to retire the sets; their final run was conducted on 28 February 2016.
One car, AE161, is preserved at Keisei's Sogo Depot.
==Design==
The AE100 series sets use a heavily raked and semi-streamlined design. A gangway door was installed for the possibility of the sets going on the Toei Asakusa Line for a potential future line connecting both Narita and Haneda Airports. The sets feature Keisei's corporate livery of Future Blue with Human Red on a Global White body.
==Specifications==
Construction of the cars is of steel. The sets use GTO drives manufactured by Tōyō Denki Seizō which produce a raspy roar, the first implementation of variable frequency drives in the Keisei fleet.
Unusually for a train the AE100 series sets feature hidden headlights; rotating flaps cover the headlights when they are turned off and retract when turned on.
