T have heard some mention of clipping the metal "hoses" on Kadee style couplers in a few threads. What I want to know is other than magnetic decoupling and simulating the air lines on the car, what good are these pins? I have gotten frustrated with a few of my cars and clipped the pins on the couplers because the pins sometimes will drag the track when using my little rerailer ramp I have here and I was wondering is there anything "wrong" with doing this to all my cars for a consistent look to them. I know the quick answer is , "It's Your Railroad, do whatever you want." But are there other uses for these pins thtat I am unaware of? Is there a detail part that could be used to better simutate these hoses?
