The trucks are chrome/silver Super, they are not covers, its quite a nice looking livery isn't it 🙂
I'm not sure about the steamer to be honest, I just saw it, liked it and it was a good price so I nabbed it. But looking at the tender it looks like an oil tank to me so I expect its oil fired. It is cool thought, the best part is that train not only has a working headlight, but also a smoke generator built in 😃 😃
I should add ALL of them have working lights 😃
