Review: The Big Boy, what a sight to behold even in N gauge. It runs so smooth especially at low speeds, it's amazing to see all those coupling rods move. This has dual motors so it can pull a hefty amount of cars without a worry. Japanese Kato locos are always reliable and easy to work on compared to some other manufacturers made in China models. It comes with instructions and front swappable pilot with coupling. Highly recommended if you are a serious model railway enthusiast. Very happy with my purchase.

This is my first Kato locomotive, and to say I’m impressed is an understatement. The model is beautiful, and while this one is just DC without sound, it still is perfect. Can’t wait to get my layout properly built to run it more often. While it’s an expensive model, Kato makes sure it’s worth every penny. The mechanism is smooth, able to perform crawls just as easily as it can run at full speed. I don’t know its pulling power, I don’t have enough cars to test, but it ran fine with the full excursion carriage set as if it had no load. 5 stars, would recommend!
