I have never heard of any sort of device to make cars rock, though some do due to inexpert assembly via loose truck screws.
There was a device that made cars coast when kicked loose by a switcher available about 30 years ago. It essentially a special underframe/floor with a large flywheel with a rubber band to a sheave on one of the car axles, and I believe developed by John Allen. I had a couple of these and they didn't work very well; the drag in a train was considerable, there was reduced turning radius for the truck, and control in those days usually wasn't fine enough for a switcher to properly kick the car. Eventually these underframes went away with my Athearn blue box cars.
On one of my portable layouts I had a spur that was sunk into the baseboard so the ties were nearly covered in dirt and a lot of Woodland Scenics foam. I had pounded on the track a bit with a hammer to make the rails uneven (code 70 Lambert track), and my cars did sway somewhat. I never had any derailment problems. It was an interesting experiment, and sinking the track is something I plan for my next layout. One spur will be sunk so the rails are embedded in street paving with cobbles or stone setts, and the other will essentially be in dirt as the track goes into a small iron works yard. I plan to use a piece of Lambert guard rail flex track for these. I'm not going to bang on the rails though.
