Reverse voltage shut down?

[JW]

Has anyone here tried using a reverse voltage on the run off area? Currently I use multiple Neo magnets glued to the bottom of the last section of track on the 6' run off section just before the bungie bag catch. Today I attached a power strip instead of the magnet attached section and ran 9 volts in a reverse configuration. It works great some cars will even roll back a ways however, some of the hopped up cars will stop and hmmm away. Which will happen at these low voltages so I don't think there is a concern... Anyone try or use this method for shut down?

I just posted some videos of the system working. Check it out JW

I messed around with it when building my track. I always kept it on low voltage. It worked but about the same as shunting the shutdown. I was afraid that some of the faster cars would probably strip gears or tear something else up.

Still use it for races over 20v. Yes low (8.5) volts in reverse. All rails are cut at the finish line. Edited to add, there is a shut off switch at the start line. Remembering to shut it off is anther issue

I use dynamic braking. I think reverse voltage will OK for most cars, but it may be too much for the Unlimiteds which are turning 100,000 + rpms.
