This model like many made today on the cheap don't last, but this isn't unusual, and this reminds me of the stuff that Bachmann used to put out every year in time for the holidays. Their advertisements would show a young boy standing over his trainset with the latest product whizzing around. The problem is the models themselves were cheap and I mean really cheaply made not the price.
Even when I was a kid, I'd cringe inside while politely smiling when I received a Bachmann model or setup. One year I got the United Aircraft Turbo train for my birthday. The setup came with a cheap transformer, really, really cheap track, a rerailer that had so much flash on it that it was impossible to use, and the trains of course weren't much better. The UAC Turbo train in this kit had oversized TALGO type connectors for the individual coaches that coupled together about 1/4-inches apart from each other. When running the trainset, the motor was way too fast, and the units were way too light causing the train to derail or stall all the time due the train leading power unit was too light and only had one power-truck. Eventually, the couplers broke on a couple of coaches from derailing way too many times, and the engine could never be weighted down enough not only to keep it on the tracks, but also to help keep the unit powered.
