I believe these are wooden Thomas the Tank Engine series tracks, but please correct me if I'm wrong. You can create a three-dimensional layout like the one in image 8 using all of them (they don't connect perfectly, but they connect with the slight flexibility characteristic of wooden tracks). I don't think there are any cracks or chips, but there is a lot of dirt. Please refrain from purchasing if you are concerned. Please check the condition carefully in the images. Please understand that these are used items before purchasing.
