Overview

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.[3][4] Built at a total cost of 800 million yen, one set was purchased directly by the Aoimori Railway, and one set is leased.[5]

Formation

The two two-car sets consist of one motored ("Mc") car and one unpowered trailer ("Tc") car, and are formed as shown below.[1]

Car No.12
DesignationTcMc
NumberingAoimori 702-1xAoimori 703-1x

The "Mc" car is fitted with one single-arm pantograph.[1]

Interior

Passenger accommodation consists of a mixture of transverse seating bays and longitudinal bench seating.[2] Passenger information is provided by LED displays above the doorways.[3] The trains are equipped with universal access toilets.[1]

History

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.[2]

Future plans

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.
