Query: Treads come off all to easy!

I purchased this for my 3 year old son and no sooner than we had taken him out of the box and ran it on the table the treads came off. I am constantly looking for the treads, or fixing them. All the other Thomas toys we have are great, but Terrance doesn't seem as durable as the others, thus making this toy in my opinion a flop.
