New Class 6050 EMUs for Tokyu

Tokyu (full name: Tōkyō Kyūkō Dentetsu, meaning 'Tokyo Express Electric Railway'), a private railway that operates its lines in the Greater Tokyo Area, has ordered 18 five-car Class 6050 EMUs. They will be used on the Oimachi Line. The first train in this batch was delivered to the Nagatsuta depot in March 2025, with the inauguration of commercial services planned for 2 July 2025.

The Class 6050 is derived from seven-car Class 6020 EMUs, which were delivered to Tokyu in 2017. The trains are manufactured by J-TREC. The seven-car and five-car EMUs have the same front ends and a similar design; they can be easily recognised by stickers reading '5 cars' or '7 cars' positioned above the emergency exit doors at the front. The five-car EMUs have an orange livery to correspond with the colour coding of the Oimachi line.

The five-car, 1,067 mm gauge Class 6050 EMUs have stainless-steel bodyshells and consist of three powered intermediate cars and two non-powered cars at both ends. Each driving car has four 140 kW traction motors, providing a total power output of 1,680 kW. The maximum speed is 120 km/h, and the trains are designed for 1,500 V DC. The traction inverters use efficient SiC semiconductors. The train offers 186 seats and space for 565 standing passengers. The air-conditioned interior includes air purifiers and reduced noise compared to older generations.

New five-car Class 6050 EMUs will replace the Class 9000 and 9020 EMUs. Sixty cars incorporated into these EMUs will be provided to Seibu Railway as part of its “Sustainable Train” programme.
