The original ones are most certainly not twaddle and have that British feel to it. The newer ones are like the Step readers and paper books; I never let my son read the new ones, but he cherishes his Complete COllection of TT Stories. We bought him the entire collection when he was 2 and he used to just flip through the pages at 2! He read them so much through the years, we had to get him a second Complete Collection of the 26 stories, because the first one fell apart! Both we bought as good, used copies.
Here’s what we got him:Thomas the Tank Engine:The Complete Collection
You may find it elsewhere(it’s at Amazon, I’m sure others), but the over shown in the above link is the complete collection with the origianal stories. The only thing I ever had to say about that I can recall is the frequent use of the word “stupid”, which we discourage strongly here.
