The fleet underwent refurbishment between 2001 and 2003, with modifications internally to improve wheelchair accessibility, and changes to the moquette seat covers. From 17 July 2010, all AE100 series trains were transferred to "Cityliner" services. Following the reduction in the  number of "Cityliner" services, five of the original seven sets were withdrawn and scrapped between 2010 and 2012, leaving just two sets in operation. 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. Two special farewell runs were organized by Keisei Travel on 21 and 28 February 2016, following which the AE100 series trains were officially withdrawn. Preserved examples. One car, AE161, is preserved at Sogo Depot in Shisui, Chiba  Prefecture.
