KidKraft Bucket Top Construction Wooden Train Set with Bulldozer & Working Crane - 61-Piece Toy Train Track Set with Storage - Perfect Gift for 3+ Year Old Boys & Girls - Great for Pretend Play, Preschool Learning & Birthday Gifts

I was a bit nervous when I bought this, because some of the reviews said that the tracks didn't fit together well, but I did not have this problem at all. The tracks wiggle a bit when they are put together, but no more than any other wooden train set. Plus, the tracks in a wooden train set should be a bit loose, because that makes it easier to set up different configurations. The tracks connecting to the bucket top were very snug, almost too snug. I definitely prefer this over a loosely fitting bucket top though, as that would cause the mountain tracks to fall apart all the time.We ended up chipping the wood on one of the tracks trying to attach it to the mountain, but luckily the piece is still usable. While the plastic bucket top mountain seems to be a snug fit, all of the wooden pieces are likely compatible with other wooden train sets. We mixed them with a Tiny Conductors set with no problems, and I plan on purchasing other brands, like Thomas and Friends, to go with it in the future.Like the other reviews said, the trains are not the greatest and do not stay on the tracks very well, so don't expect much in that department. We ended up using different sized hot wheels cars on the tracks instead. Thanks to the other reviews, I expected the trains to be crappy when I bought the set, so I am not disappointed. Assembly was not too difficult, but the instructions were unclear about which length of straight pieces should go where, so I give it 4 out of 5 stars for assembly. Overall, it's not a perfect product, but the bucket top mountain and other pieces are really fun, and I think it's a great purchase for the price. I especially like how unique some of the pieces are, like the mountain and the rock quarry, which was my main reason for purchasing it. I think those unique pieces will make it fun to play with again and again. I am already planning to buy one of the other sets from this brand when I have the money for it.
