The interior includes passenger information displays, security cameras,[6] and wheelchair spaces.[7] Seating accommodation consists of longitudinal seating throughout and includes foldable seats, in order to provide more space for luggage.[5] In addition, the seat backs are approximately 170 millimetres (6.7 in) higher than those of the 3000 series.[5]
Two eight-car sets were built in 2019.[5] The trains entered service on 26 October 2019.[8] Delivery of a third set, set 3153, began on 7 July 2020.[9]
On 29 September 2021, it was announced by Keisei that new sets 3155 and 3156 were expected to enter service on 12 November and 30 September 2021, respectively. These two sets differ from preceding sets as they feature ladders at the end of cars 1 and 8 to allow for quick evacuation in the event of an emergency.[4][needs update]
The 3100 series and Shin-Keisei 80000 series trains were jointly developed.[10][11]
In early 2023, Keisei announced that an additional set would be purchased as part of its 2023 capital investment plan.[12] This set entered service on 18 June 2023.[13]
