Design
Based on the 3100 series design[5] introduced in 2019,[6] the 3200 series was designed as a "flexible train", allowing trainsets to be arranged in 4-, 6-, or 8-car formations as needed. The trains use silicon carbide-based VVVF traction control systems, offering 69% energy savings over the traction systems used with the 3500 series trains.[5] The external information displays are automatically disabled at speeds of at least 70 kilometres per hour (43 mph) and re-enabled at speeds of at most 65 km/h (40 mph), offering further energy savings.[3]
To facilitate multiple working, the 3200 series adopts electrical connectors to allow for easier dividing and joining, a first for Keisei. Previous train types used jumper cables to facilitate such operation.[7]
Internally, the trains use LED lighting throughout. Passenger accommodation consists of longitudinal seating. Wheelchair spaces are provided in the end cars, and free spaces for strollers and large luggage are provided in the intermediate cars.[5] Pairs of 17-inch LCD information displays are provided above each passenger door.[8][9] As a weight-saving measure, the 3200 series uses standard-height seat backs instead of the high seat backs used with the 3100 series.[2]

Operations
The 3200 series is slated to replace the ageing 3500 series fleet as well as older trains operated by Shin-Keisei Electric Railway after its merger with Keisei in April 2025.[9] The fleet is primarily used on Keisei Main Line and Chiba Line services,[3][10] with plans to deploy the type on Kanamachi Line services in the future.[11]
Formation
The 3200 series sets are formed as shown below. All cars are motored, although the "M2" and "Mc2" cars only have one motored bogie.[3]
| Car No. | 4 | 3 | 2 | 1 | |
|---|---|---|---|---|---|
| Designation | Mc1 | M2 | M1 | Mc2 | |
| Capacity (total/seated) |
120/39 | 133/49 | 133/49 | 120/39 | |
| Weight (t) | 34.9 | 31.5 | 33.9 | 32.7 | |
- The "Mc1" and "M1" cars are each equipped with one single-arm pantograph.
History
The first six cars, 3201–3206, were delivered from the Nippon Sharyo plant in July 2024.[12][13] Japan Transport Engineering Company (J-TREC) was also contracted to manufacture 3200 series sets.[9]
The 3200 series first entered revenue service on 22 February 2025.[4][11] On 21 May 2025, Keisei announced plans to procure 90 additional vehicles from fiscal 2025 to 2027.[10] This order was reduced to 88 vehicles in November of that year.[14]
