Kato - 5017 - Passenger Car, Commuter, JNR Series 12 - Japanese National Railways

Prototype History: The series 12 was a popular passenger coach design produced in Japan from the late 1960s through the 1980s. It was introduced in Japan in 1969. These were designed to be pulled by steam or diesel locomotives. They were built at the JR East Takasaki vehicle center. This design was updated several times during their production history. The Suhafu 12 was an example of a later production run.

Road Name History: Japanese National Railways (日本国有鉄道 Nihon Kokuyū Tetsudō), abbreviated Kokutetsu (国鉄) or "JNR", was the business entity that operated Japan's national railway network from 1949 to 1987.
By 1987, JNR's debt was over ¥27 trillion ($280 billion at 2009 exchange rates) and the company was spending ¥147 for every ¥100 earned. By an act of the Diet of Japan, on April 1, 1987 JNR was privatized and divided into seven railway companies, six passenger and one freight, collectively called the Japan Railways Group or JR Group.
