733 series


The 733 series is an electric multiple unit train type operated by Hokkaido Railway Company on suburban services in the Sapporo area of Hokkaido, Japan, since 1 June 2012.

Variants

Similar in appearance to the aluminium-bodied 735 series EMUs built in 2010, the 733 series EMUs have stainless steel bodies with steel driving cab ends. At 2,892 mm, the 733 series cars are also wider than the 731 series and 735 series cars, which are 2,800 mm wide. Sets B-113 onward, delivered from September 2013, feature full-colour LED destination indicators, instead of the three-colour indicators used on earlier sets.
Five new six-car sets, classified "733-3000 series", were delivered in 2014 and phased in on Airport rapid services between and from July, operating alongside the existing 721 series EMUs, and allowing the withdrawal of the remaining 711 series EMUs still in service. These sets include a "u Seat" car with unidirectional reclining seating for reserved seat passengers. The new sets feature LED lighting in the passenger areas.

Operations

The 733 series sets entered service from 1 June 2012 on suburban services in the Sapporo area of Hokkaido, including the newly electrified Sasshō Line. They are capable of running in multiple with 721 series, 731 series, and 735 series EMUs, but, unlike the 731 series, cannot operate in multiple with the KiHa 201 series DMUs also used on the Sasshō Line.
