Cutting the coupler hoses down, dragging on turnouts...

[tomustang]

If you mean the wire on the Kadees(as well as the other manufacturers) used for magnatic uncoupling....
I usually bend them up with a small pair of pliers. Kadee, does make pliers specially designed for the job. But if you're carefull, regular needlenose work just as well.
I have read that some people do cut these off, because they are not gonna use the uncoupler ramps made by Kadee.

I'll try the bending next time
