I was struck when extracting it from the well-designed packaging by its mass. Remember, the real things were designed to carry tanks, they were not lightly constructed. The model is unlikely to derail due to lack of weight, unlike some bogie wagon models which only run well when laden. I'm also impressed by its free-running properties, I have discovered undetected gradients on my layout since shunting this around the sidings. The decoration is first class, and the NEM pockets at the perfect height for my preferred KD couplers. A real pleasure to own one, thanks Accurascale!
