Thanks HANDYANDY for sharing this!
I will try to make a review video on this tomorrow. It is clearly a knockoff of Lionel's Polar Express set, with the same font being used for "North Pole Express." There are two variations of this set: one with green cars and one with brown cars. I purchased the one with brown cars. The set was tucked away in the back of my Walmart's holiday section. For $10 it is a nice set. The passenger cars are very nice.
I consider myself to be a traditional O gauge hobbyist, but I like the Chinese knockoff stuff (mainly for the laughs).
