The DCC controlled coupler is shown on the left. Note normal lip on coupler knuckle (Fig 1-A) has been removed on the DCC controlled coupler. (Fig. 1-B) This allows the uncoupler to actuate even under slight tension.

The knukle stop (Fig 2-A) has been filed back to allow the knuckle to open completely. File till the tip of the knuckle will open even with the end of the pocket. (Fig 3-A) This is needed in order to uncouple reliably on curves by just moving one knuckle.
