Because it's TRW, I just want to reiterate how much I despite plastic rail joiners. But, of more concern, are the huge rail gaps you have in these joiners. I realize that there's supposed to be a gap (the little prong that keeps the rail ends apart), but it doesn't appear that the rails are fully inserted into the rail joiners, leaving some monster gaps. Compare the farthest rail (the smallest gap) to the closest rail and the third rail back, for example. Ew.
Oh, and you also have a hump at the joint nearest the camera. Are the replacement ties under the rail joiners causing this?
