I purchased a Fastrack terminal section from one of the forum sponsors about 6 months ago that had the same issue (i.e. it was missing the c-clamps that were meant to be attached to the ends of each wire as pictured on the box). I reached out to the dealer, and the store examined the rest of their in stock inventory only to discover that all of the other pieces were exactly the same. At that point, the dealer told me that there was nothing they could do and suggested that I contact Lionel. Instead of contacting Lionel, I just used the wire as is and it's been fine for my modest layout.
