Why ? very simple the original Lionel transformers were built before the times of UL approved, before the times of grounded outlets. It was not that long ago then that electricity was still a mystery and the majority of homes did not even have electricity. Frankly the concept of safety, probably did not occur to anyone, or they would have insulated the outside metal plates. This is why every transformer we refurbish, not only adds a 3 prong plug for safety, but also takes care of phasing issues. Common guys common sense works even today.
