This was the first add on car that I purchased for my Polar Express train set. The second and only other one thus far being the Diner car....see my review. I had a couple HO sets when I was a kid in the early 80s. Thats about the extent of my model railroad hobbying. Bought the Lionel O scale Polar Express set for Christmas this past year to run around the tree and delight my sons. First thing I had to do was purchase more track as the amount included in the set was not enough to delight myself let alone my boys. Then I looked into making the train longer and was happy to find there were several add on cars. Which leads me to my question. Good Lord, these cars are expensive. Especially for what they are - plastic. Sure they have lights inside, but I don't see $65 here. And over $100 for the one with sound? Factor in the original set cost about $300, the extra track I've purchased and the two add on cars, I have nearly $1k invested in this thing. So am I happy with it? Yes. I just think it's a little pricey for what it is. Let me reiterated that I'm a civilian when it comes to model railroading so I don't know if this is the norm for O scale trains.
