Working HO Air Hoses

[e-paw]

I like the idea.. It's pretty cool to see em in action. At the present cost, I hope it comes down, It would take a several hundred dolor investment to equip all my locos, cars and cabooses. so I think I will hold off on it for now. I would like to play around with them a little to see just how they work. If I could find small enough magnets I could probably make something similar.
