Lionel ZW 275 Transformer reconditioned with new features never done before

The answer is simple. Here briefly is what they did. These windings were coated with varnish, on their sides, so they would not short each other out. Therefore what do is change the original breaker to a modern design that works much faster than the original Lionel designs.
