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!

Exactly as described, Safely packaged with plenty of padding - Box and Kato train in showroom condition - awesome performance - looks magical when running and is the real centrepiece when it is on my layout.

The KATO Union Pacific Big Boy in N scale is top of the line quality model train. The basic build of the model train is sturdy, mostly Diecast. The surface detail is Unbeat on this model.The connecting rods look amazing whether it’s stationary or moving. And this locomotive moves fast and hauls a lot of cars. The model works on Bachman tracks not just KATO track, which is great if you’re trying to save money on cheaper tracks. And I was able to get the coupler to latch onto the Bachman train cars. Overall, very very pleased worth the money.
