Design
Built by Nippon Sharyo in Aichi Prefecture, the N800 series design is based on the Keisei 3000 series EMU. Although built as 6-car sets, the units are designed to be lengthened to 8-car sets in the future if required.[1] The N800 series is also intended for use on inter-running services to and from the Keisei Chiba Line.[2] The sets have a maximum speed of 120 km/h (75 mph), but only operate at 85 km/h (55 mph) in service.[1]
Formations
As of 1 April 2015[update], the fleet consists of three six-car sets based at Kunugiyama Depot with four motored (M) cars and two trailer (T) cars, formed as shown below, with the Mc1 car at the Tsudanuma end.[1][3]

Interior
Passenger accommodation consists of longitudinal bench seating throughout. Each car has priority seating at one end, and the two end cars each have a wheelchair space located close to the cab end.[1] Some of the bench seats have metal steps on the underside, allowing them to be detached and used as steps for evacuating the train in emergencies.[1]
History
The first set, N811, entered service on 29 May 2005.[4]
The first set to receive Shin-Keisei's new pink corporate livery introduced in 2014 was N821 in February 2015.[5]
The fourth set, N841, entered service on 22 December 2015. It is the first Shin-Keisei trainset to feature LED lighting and LCD passenger information displays from new.[6] A fifth set, N851, was delivered in August 2018,[7] entering service on 22 August of that year.[8][better source needed]
On 24 July 2024, set N831 returned to service in the original livery with maroon waistline stripes.[9][10]
On 1 April 2025, all sets were transferred to Keisei following its acquisition of the Shin-Keisei Electric Railway.[11] Beginning in July of that year, the N800 series fleet received the standard livery based on that of the Keisei 3000 series.[12]
