Plarail 103 Series Help

Hi guys, I have recently fell in love with the plarail 103 series commuter trains and also while on my trip in Japan caught this commuter train on the Osaka loop line whilst going to and from school.




I know plarail has produced many variants of this train but I just need help with locating where these 103's came from like what set it packs they came in. The only one that I know where it came from was the orange Osaka loop line 103 which was a plarail store exclusive.

This orange one here


This is a pretty good photo of some of the different 103's you can get



There are green, dark green, blue, yellow, orange and beige variants of these trains and I just want to know where these variants of the 103 where found like what set or pack they came in. If you could provide photos of some of the packs or sets that these 103's were found in that would be greatly appreciated.
