These were by far the best value I could find for replacement rubber grips for my son’s Thomas The Train Trackmaster engines. They TECHNICALLY fit, HOWEVER, you MUST GLUE THEM for them to stay on. Just put the grips on the wheels, buy some super glue, turn the engine on, and SLOWLY apply a small amount of super glue to the outside of the wheel where it meets the rubber, let it dry for 30-60 seconds, then apply it to the other side of the wheel. As you can see in my photos, the new grips (on the green #6 train) are not the exact same as the original gray ones in the yellow #22 train, but they work fine.
