I waited until Yesterday to decide whether to buy, or not to buy, thinking about all of the features, Which I Personally Think are So Neat, so, I could not resist, I Bought the 4014 VL BIG BOY. It does not matter about the Coal Depleting, It's all of the other Features.
I have the Legacy Big Boy and it's great, But, This one is Fantastic. Happy Railroading.
