Tonight I was designing a coupler pocket to fill the gaping hole in the pilot face. Something to represent a real coupler pocket. While making some measurements, I come to find that the distance from the pilot face to the coupler pulling face is almost prototype distance. I was fairly impressed. It is just a tad longer, but very close. The ture prototype distance is 25". In N-scale that is 0.156" and I measred about 0.162" on the Kato coupler.
What is it about them that causes them to suck?
Are MT couplers the only other option for the Kato SD40-2?
For me, the Kato factory couplers would not always stay coupled (even to each other). Nothing quite like having a consist split up while trying to pull a long train upgrade...
Hmmm...The Kato SD40-2s certainly have come with some different couplers over the years. I'd be curious which version you have.
Are MT couplers the only other option for the Kato SD40-2? I do not like the spring action in them, but what about making a bushing that makes the MT coupler a solid swing without the spring?
