New Automatic Magnetic Brake Lines

I saw this new cool product from North American Railcar Corporation called High Performance MagnaLock Brake Lines. They are automatic coupling and uncoupling brake lines for your rolling stock. They work on curves up up to 180^o. They are $24.98 for 10 pairs.

Here is the website:

And here is a video:


I would love to see this magnetic technology also applied to diaphrams for passenger cars. Rubber diaphrams that automatically come together and apart and that stay together around curves would greatly enhance realism on passenger trains.
