Japanese Diesel multiple unit "KIHA-40 Series"

I am writing today about the Japanese Diesel multiple unit which I introduced yesterday.
This Diesel multiple unit is "KIHA-47-8000, KIHA-140-2066,KIHA-147-1045".
The number of the Japanese train has a rule.
"KI"is Diesel multiple unit."HA"is Third Class Car till 1960.
Now,Japanese trains have two classes.
One is "Green car"(Second class car).This number is "RO".
The other is " Standard car".(Third Class Car)
What is the number of the first-class car which existed till 1960.
The first class car was "I".
"I,RO,HA"is one of the arrangements of a longtime Japanese word.
It is also a Japanese song;"I,Ro,HA,NI・・・"
It resembles the alphabet;"A,B,C,D・・・"
KIHA47, KIHA-140, and KIHA-147 belong to the same series.
That is the "KIHA"-40 Series.
Japan National Railways(JNR) made a total of 888 of these cars From 1977 to 1982.
JNR used it for the line in the whole country which was not electrified. However, JNR were privatized in 1987 and JNR became the present JR.
Each JR company has many "KIHA-40 Series" of this form even now.
Japan Railways group companies converted this "KIHA-40 Series"according to the special features of the area. Therefore," Hayato No Kaze" is the very characteristic body.
The "KIHA-40 Series" railroad model has many designs.
It is the same as that of actual cars.
This model is indispensable in order to reproduce the scenery of the districts in Japan. At the local station in Japan, these cars are often seen.
