@Dave_C posted:Pretty much every 3 rail rail car has couplers that will open with a magnet. The magnet is in the track and is operated with voltage from a push button. These couplers are usually referred to as thumbtack couplers. The magnet pulls down what looks like a thumbtack and the coupler opens.
yes, but then why does the box say specifically "Magnetic couplers"? every car we own has the flap or the thumbtack, and none of their boxes say "magnetic couplers". If these aluminum cars require a specific button or piece of track to operate, they're probably best left until we buy a house and eventually build a more permanent layout. Right now, we're annoying the wife and running trains through the kitchen and around the inside wall of the house under furniture. (She tolerates it because the kids love it and they're quiet except for giggles when the trains run)
