Backward Magnets, Cool Train

Mrs. Scott bought our two oldest some wooden trains, and they fit the Thomas track, but are a third party brand. Only problem is that the polarity of the magnets that act as couplers are reverse from the Thomas brand trains so that cars could not be mixed together. But anxiety was soon turned to blissful joy for all of us when we discovered that an engine could then be placed at the end of the train, facing backward, just like real trains. This one we could not do with mere Thomas trains. Cool.
