The is an electric multiple unit (EMU) train type operated by the third-sector railway operator Aoimori Railway on the Aoimori Railway Line in Aomori Prefecture, Japan, since March 2014.[1]
Based on the JR East E721 series EMUs first introduced in 2006, two two-car 703 series trains were manufactured by J-TREC in Yokohama, Kanagawa.[2] Built at a total cost of 800 million yen, one set was purchased directly by the Aoimori Railway, and one set is leased.[3]
The two two-car sets consist of one motored ("Mc") car and one unpowered trailer ("Tc") car, and are formed as shown below.[4]
| Car No. | 1 | 2 | |
|---|---|---|---|
| Designation | Tc | Mc | |
| Numbering | Aoimori 702-1x | Aoimori 703-1x |
The "Mc" car is fitted with one single-arm pantograph.[4]
Passenger accommodation consists of a mixture of transverse seating bays and longitudinal bench seating.[1] Passenger information is provided by LED displays above the doorways.[5] The trains are equipped with universal access toilets.[4]
The two sets on order were delivered from J-TREC's Yokohama factory to Aomori in November 2013.[6] The two sets entered revenue service from the start of the revised timetable on 15 March 2014.[1]
Effective the timetable revision on 18 March 2023, 703 series will operate as far south as Sannohe Station on the Aoimori Railway Line.[7] Trains currently only operate as far south as Hachinohe Station.
