Geesh...I just can't find the page I was looking for with the engines and rolling stock give aways at the various Plarail Expos.
Here is what I think I remember, the engine on the right I believe was a prize children received by playing a couple a games at the Expos. I believe that the engine on the left was also a prize and this style is a remake of the original engine design that I think was released about 1961.
In this 2011 Tokyo Plarail Expo video, starting at the 3:30 minute mark, you can see the childrens Fishing Game with all the engines ready to be caught. Look closely and you can see your engines in the box.
