In December 1985, KiHa 59 was remodeled from KiHa 26 and KiHa 56 cars at the Naebo plant in Sapporo, Japan. It was the last resort train to be introduced by the Japanese National Railways which was privatized to be separated and destined to JR Hokkaido in Hokkaido region. The train was initially called "Alpha Continental Express" and started operating on the Ishikatsu Line as a chartered tourist train. It attracted widespread attention due to its design and facilities, and was operated as a group chartered train, and been offered temporary limited express trains all over the country against the backdrop of the resort boom before and after the era.^{[citation needed]}

The Alpha Continental Express was nicknamed as "Alcon" which they only used when contracted transportation with both Tomamu and Sahoro resorts, and they also offer other services used such as "Resort Express", "Peppermint Express", and "JTB Panorama Express".^{[citation needed]}

Although it was popular during that time, they also encountered different problems which became apparent when the newer rolling stocks introduced. The maximum speed was limited to 95 km/h, which made it difficult to adapt to the timetables of newer JR Hokkaido express trains, which they are struggled to perform on the lines to be arrived and depart on-time.^{[citation needed]}

It has been used for nearly 10 years since the conversion and nearly 30 years since being manufactured in the 1960s. It was withdrawn in 1995.^{[citation needed]}

The Alpha Continental Express trainset was formed as follows (1985 – 1995). They also offered in different train services in Hokkaido region such as "Resort Express", "Peppermint Express", but not "JTB Panorama Express" which they add one carriage in 1986, resulting in a four-car formation.^{[citation needed]}

They also operated the special train service called "JTB Panorama Express" trainset which was formed as follows (1986-1995).^[2][3]

JR West introduced their "VIVA West" Joyful Train service in 1989.^{[citation needed]}

It was formed at JR West Hiroshima works after "Resort Saloon Fiesta" train services in 1989 by remodeling former KiHa 28 and 58 series cars. The remodeling work was carried out at the Habu rolling stock plant (now the Shimonoseki General Rolling Stock Office).^{[citation needed]}

It was also temporarily used as a passenger train for short train services, and ended operation after nearly ten years and was scrapped in March 1999.^{[citation needed]}

The Viva West trainset was formed as follows (1989 – 1999).

In its operations under the Philippine National Railways, it served as an intercity train and premiere train, but its windshields had to be armored with steel mesh to prevent the glass from being pelted by train stoners.^{[citation needed]} The unit underwent general renovation and overhaul in 2019.^[9] The armoring was later removed when the livery was updated to match the newly arrived PT-INKA livery, along with the updating of the windshields into more durable polycarbonate panels.

On 20 September 2019, the PNR Kogane trainset was used on test run and clearing operations on the Calamba-Los Baños section of the PNR Metro Commuter Line.^[10] Kogane also went to Legazpi for the inspection of the PNR South Main Line together with 917 prior to the PNR South Long Haul project.^[11]

The Kogane trainset in service with Philippine National Railways is formed as follows.^[9]

• In July 2012, the Kogane train derailed near Lopez, Quezon.

• In February 2020, a window in the Kogane trainset shattered due to a stoning incident.^[12]
