Coupler Slack Action in G Scale

I always get people commenting on the slack action that the good body-mounted kadee couplers get in G Scale so I made a short video of this train backing up. The engines are running at the same speed through the entire video, but the train has a slight jerking action as the couplers have slack in them that is taken in and out as the cars roll along.

This video was uploaded from an Android phone.
