Keisei AE100 series

The Keisei AE100 series (京成AE100形) was a DC electric multiple unit (EMU) train type operated between 1990 and 2016 by the private railway operator Keisei Electric Railway on Cityliner limited express services between Tokyo and Keisei Narita in Japan. First entering service in June 1990, the trains replaced the earlier AE series EMUs operating on Skyliner services providing a link between Tokyo and Narita Airport. They had a slant-nosed design with hidden headlamps.[1]

History

The first trains were introduced from June 1990, replacing the earlier AE series sets.[5]

The fleet underwent refurbishment between 2001 and 2003,[5] with modifications internally to improve wheelchair accessibility, and changes to the moquette seat covers.[3] From 17 July 2010, all AE100 series trains were transferred to Cityliner services.[4]

Following the reduction in the number of Cityliner services, five of the original seven sets were withdrawn and scrapped between 2010 and 2012, leaving just two sets in operation.[5]

From the start of the revised timetable on 5 December 2015, regular Cityliner services were discontinued, leaving the two remaining AE100 series sets without regular duties, although seasonal services were scheduled to continue until the end of January 2016.[6] Two special farewell runs were organized by Keisei Travel on 21 and 28 February 2016, following which the AE100 series trains were officially withdrawn.[7]

Preserved examples

One car, AE161, is preserved at Sogo Depot in Shisui, Chiba Prefecture.[8]
