The 1.5kV dc 1067mm-gauge trains were ordered in 2014 to replace the ageing 103 and 201 series EMUs currently operating on the 21.7km Osaka Loop. Each stainless-steel-bodied car has three doors on each side and the trains are equipped with CCTV, passenger Wi-Fi, LED interior lighting, and multilingual passenger information systems.

The first of the 100km/h EMUs will be introduced later this year and the remainder of the fleet is due to enter service by the end of the 2018 financial year.
