The original box is included. Please see my high-quality photos for a detailed look at this item. When I carefully inspected the Locomotive, I lubricated the engine and transmission as well as all axles.
I tested it on my analog and digital train set, and it runs smooth and silent in forward and reverse mode including the light and multiple sound functions. The digital address is set to #78 and can easily be changed by pulling off the tender's coal bed and resetting the dip switches. It will automatically switch to analog or digital mode as required.
It's ready to go! Please feel free to contact me with any questions you might have.
