Lilac 789-0 series A total of 40 cars were built between 2002 and 2005 for use on new Super Hakuchō services introduced from 1 December 2002 between ( from December 2010) and via the undersea Seikan Tunnel coinciding with the opening of the Tōhoku Shinkansen extension to Hachinohe. The trainsets were formed as four 2-car half sets, HE-101–104, and five 3-car half-sets, HE-201–205, which were coupled to produce 5- or 8-car formations. From December 2005, new SaHa trailer cars were added to the original 2-car sets HE-101–104, and a fifth set, HE-105 was delivered. Two additional 2-car sets, HE-301 and HE-302, were also delivered for extending trains to up to eight cars during period seasons. Two new 3-car sets, HE-106 and HE-206, were delivered in April 2011. In March 2016, Super Hakucho services were discontinued because the new Hokkaido Shinkansen services ran on the same route, this meant that the 789-0 services (along with the series trains) operating on the Super Hakucho services were completely taken out of service. From the start of the revised timetable on 4 March 2017, Lilac limited express services were reintroduced between Sapporo and Asahikawa using six-car series EMUs previously used on Super Hakucho services until March 2016. These services complement the Kamui services using five-car series EMUs. Formations (There is no information on the Lilac service formations yet.)
