Plarail TOMY Thomas NEW RELEASES

could it be that Plarail has done so many trains of Japan that they are running out of new ideas? 

How could that be even possible? I mean, I really like their commuter trains, and this Tokai doppelgänger is a nice train, but they really have so many nice commuter lines in Japan! When I watch train videos from Japan, I often catch myself thinking: Wow! This one would be just perfect as Plarail model train! And that one! And that one too! They just can't run out of ideas for train models in Japan. 😊

I'm not familiar with the process they must undergo before producing a model train. Some of the trains they are making in co-production with railway companies, but what about others? Do they have to ask for permission to make a certain model train? Then there are moulds; it's obviously easier to make something with the existing moulds, so there is no ton of really new models, I can understand that... On the other hand, there are many new colouring schemes that can be used on already existing moulds, but they keep re-releasing the same model in the same colours... 

But if they lack ideas, that's really strange, because they have really a huge number of beautiful trains right before their eyes.
