Actually the trains (M Train to be exact) were built in 1979. They were refurbished with new front end as depicted in the Tomy train in 2008
I found a photo of a M Train with original front end. I am having trouble inserting the image here for some reason. Anyways, I attached the link below for you to click

As you can see, it does resemble one of the JR train (I can't remember the name of that train) but it has silver livery with green stripes.
