Coupler problems?

Mike, what Doc said about the coupler height.  Hence my reason for asking that question.

Also, you can find the couplers by searching the net elsewhere for better prices.

Ok, i'll go with the same coupler (Item #78025-Center shank medium).

On another matter, can you or anyone please tell me the proper order of model train sizes starting from the smallest to the largest?
