RARE! This listing is for FOURTY-EIGHT (48) Vintage 1999 TYCO Toys Inc., 440-X3, HPX3 RARE EARTH, COBALT, TRACTION MAGNETS. The story is that TYCO Toys was sold to Mattel Co. right around 1999. At that time, TYCO had nearly developed a next generation chassis with a (blue) armature & Rare Earth Magnets for SUPER GRIPPING POWER. The issue that arose in real life use was that, the friction & torque of the chassis combined to literally melt the plastic alongside the rails ON SMALL 8' long Starter Sets! (They should pose no problem on longer tracks where the rails have a chance to dissipate some of the heat from the friction.) Quite a problem seeing they had already produced X-3 Literature & some packaging for international cars & sets. NONE of the Packaged 440-X3 HPX-3 Vehicle or sets have the rare earth magnets, although Racing Warriors are commonly found with the (better?) Blue Armature. These are factory direct & i am describing them to the best of my knowledge. I have other listings with the Magnet Plus Plastic Holder that together, mimic a 440-X2 traction magnet. These would be for advanced enthusiasts that want to custom fit these. There may be in other listings the plastic holder that adapts a typical 440-X2 magnet to 440-X3.
