Looking at my trusty Plarail 60th Anniversary Book and since this 151 Series Kodama is 10 years old (50th Anniversary Edition) it was released in 2009. Looking at the bottom example of your picture it looks like a mis-match train, possibly each piece from a different set. The left engine looks to be the 50th Anniversary Edition. The middle coach looks to be from the 485 Limited Express released in the same year. That right faux engine needs further research as it doesn't appear to be from the 50th Anniversary set with its different window configuration and wide red stripe. Wonder if there was a much earlier release of this train. So my guess would be that the bottom one could not have been new in the box when purchased. Are these yous Vio?
EDIT:
There were 2 earlier releases in 1971 and 2002 but nothing like the right on the bottom in your picture so that mystery goes on. I do like this train (don't have one) to me it has that vintage car look of the 40, 50 and 60's
