I have a dilemma... I own one Custom Rail, Tri-level auto rack, and parked next to a Walthers Bi-level (or tri-level), Accurail 89' flat, or Walthers 89' flat, it sits noticeably high. But the thing I don't get is the coupler pocket comes out just about the same. What I'm getting at, the main question, is the Custom Rail car too high? Is there a prototype, tri-level, or bi-level at the higher height? Or is the matching coupler pocket just compensating for the higher height? Here's an example, Custom Rail car to the left, Walthers to the right.
