The running gear was based on the KiHa 201 series trains introduced in 1997, and the body design was a joint venture with the Danish State Railways (DSB).[2]
As of 1 April 2013[update], 35 KiHa 261 series vehicles were in operation.[3] 14 were built by Fuji Heavy Industries, and 21 were built by JR Hokkaido.[3] A further 28 vehicles are on order to be delivered from fiscal 2015.[4]
KiHa 261 series trainsets are used on the following services.[1]
Sōya services are normally formed of four-car KiHa 261-100 series sets, and are sometimes lengthened to six cars during busy periods.[5]
Four-car sets are formed as follows.[5]
| Car No. | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Numbering | KiRoHa 261-200 | KiHa 260-200 | KiHa 260-100 | KiHa 261-100 |
Six-car sets are formed by adding two cars as shown below. Car 1 (and car 21) includes Green (first) class and standard class accommodation.[5]
| Car No. | 1 | 2 | 3 | 4 | 5 | 6 | |
|---|---|---|---|---|---|---|---|
| Numbering | KiRoHa 261-200 | KiHa 260-200 | KiHa 260-100 | KiHa 261-100 | KiHa 260-100 | KiHa 261-100 |
| Car No. | 21 | 22 | 1 | 2 | 3 | 4 | |
|---|---|---|---|---|---|---|---|
| Numbering | KiRoHa 261-200 | KiHa 260-200 | KiRoHa 261-200 | KiHa 260-200 | KiHa 260-100 | KiHa 261-100 |
Super Tokachi services were originally formed of five-car KiHa 261-1000 series sets, but these were later reduced to four cars.[1]
The 4-car Super Tokachi sets are formed as follows.
| Car No. | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Numbering | KiRo 261-1100 | KiHa 260-1100 | KiHa 260-1200 | KiHa 261-1200 |
A four-car pre-production set was delivered from Fuji Heavy Industries in November 1998 for evaluation and testing.[1][2] The first production trains were introduced on Super Sōya services between Sapporo and Wakkanai from the start of the revised timetable on 11 March 2000.[1]
New KiHa 261-1000 series 5-car sets were introduced on Super Tokachi services between Sapporo and Obihiro from October 2007.[1]
A further 28 KiHa 261 series vehicles were delivered from 2015 onward, and these are not equipped with tilting capability.[4]
From December 2015 until the end of 2017, the KiHa 261-1000 series fleet were gradually repainted into a new livery with white front ends, yellow front-end gangway doors, and a purple bodyside stripe.[6]
On 17 October 2019, JR Hokkaido announced plans to introduce two new KiHa 261-5000 series 5-car sets.[7] They each feature external colour schemes inspired by the hamanasu and lavender flowers, which, according to JR Hokkaido, are prominent throughout Hokkaido.[8]
Car 1 is designated as a lounge car, featuring window-facing seats and transverse seating bays with tables. Cars 2 through 5 are ordinary-class cars, featuring 2+2 abreast seating throughout.[9]
The "Hamanasu" set was built at Kawasaki Heavy Industries' Hyogo factory, and was delivered to JR Hokkaido in July 2020.[10] It entered revenue service on 17 October of that year.[11] The "Lavender" set was delivered from the same factory in January 2021[12] and entered revenue service in May of that year,[13] although it was originally intended to enter service in April.[8]
