Operations

Based at Kagoshima Depot, the fleet of four 2-car 713 series trains are used on Nippo Main Line services.[3]

Formations

The 2-car sets, numbered LK1 to LK4, are formed as follows.[3]

Designation McT'c
Numbering KuMoHa 713KuHa 712

The KuMoHa 713 car is fitted with one PS101D lozenge-type pantograph.[3]

External livery

When delivered, the trains were originally painted in cream ("Cream No. 1") with green ("Green No. 14") bodyside bands, matching the 715 series EMUs.[4] Between 1986 and 1987, the sets were repainted in the standard Kyushu livery of white with blue bodyside bands.[2]

In 1996, the fleet underwent refurbishment and was repainted in a bright red "Sunshine" livery with blue doors.[2]

History

The 713 series sets were delivered from July 1983, built by Hitachi and Tokyu Car Corporation, and becoming the first AC-only EMUs to operate in Kyushu.[2] They entered service from the start of the February 1984 timetable revision, operating on the Nagasaki Main Line and Sasebo Line, and based at Minami-Fukuoka Depot.[2][4] Because of their somewhat experimental nature, the cars were originally numbered in the KuMoHa 713-900 and KuHa 712-900 series.[4]

Interior of set LK904 in 2007

Coinciding with the opening of the Miyazaki Airport Line on 18 July 1996, the fleet underwent extensive refurbishment and were transferred from Minami-Fukuoka Depot to Kagoshima.[2] Internally, the fixed transverse seating bays were replaced with pairs of new reclining seats which could be rotated to face the direction of travel.[2] Externally, sets received a new bright red "Sunshine" livery with blue doors.[2]

The fleet underwent further modifications to allow the sets to work on wanman driver-only operation services commencing from October 2003.[2]

Between 2008 and 2010, the fleet underwent a second life-extension refurbishment programme, primarily designed to standardize the electrical equipment built by different manufacturers. At the same time, the individual cars were renumbered from the -900 subseries to the -0 subseries, and the sets were renumbered LK1 to LK4.[2]
