Design

The 5500 series were built by Japan Transport Engineering Company (J-TREC) as part of its "Sustina S13 Series" family of 18-metre (59 ft 1 in)-long, three-door stainless steel-bodied trains.^[1] The new trains have a maximum operating speed of 120 km/h (75 mph), compared to 110 km/h (68 mph) on the majority of the earlier Toei 5300 series fleet. In addition, they use energy-efficient three-phase induction motors controlled by two-level variable frequency drives using silicon carbide-based MOSFETs.^[2]

Operations

They are used on the Toei Asakusa Line, Keikyu Main Line, Keikyu Airport Line, the Hokuso Line and the Keisei Line through services since 30 June 2018. They were introduced on Narita Sky Access Line services on 26 February 2022.^[3]

Formation

As of July 2021, the fleet consists of 27 eight-car trainsets. The formations consist of 6 motored ("M") cars, and two non-powered trailer ("T") cars. Car 1 is on the south end.
