These will work with Thomas the train and Brio railroad track, however, they aren't a perfect fit. They don't nest perfectly with each other like the name brand, but they will still let the train pieces roll over them. Some pieces are branded as "Nuchi". These are played with and show signs of cosmetic wear, marks, scratches, nicks, etc. Message us with any questions or concerns!
