This vehicle has been maintained by an amateur so that you can enjoy it for a long time. Of course, the operation has been confirmed. My operation check means confirming that it runs properly. It's not just "it moved when I put in batteries, so it's good!" The usual set includes a railroad crossing, a station, and a car wash gimmick rail, but this set also includes a bridge gimmick rail. The sound also works properly. To ensure a smooth transaction for both parties, please feel free to comment if you have any concerns or would like additional images. Seriously, please refrain from contacting me if you are overly concerned about details. I have other items for sale. If you would like to purchase multiple items, please use the "request combined purchase" function to consult with me. I will almost always accept requests, except for manually entering your desired price. Please also take a look at my profile. For those interested, please see below. Here are the maintenance details. ★ Removal and cleaning of dust, hair, etc. around the wheels and motor unit of the power car. There may be some parts that cannot be completely removed. ★ Independent maintenance of the motor. Restoring the motor to its original condition. Since I have not replaced it with an aftermarket motor, you may be able to request repairs from the manufacturer. They will not accept modified products. ★ Cleaning of the exterior using various cleaners. The above is the maintenance content. I have not done anything more than this. I hope we have a good relationship m(_ _)m
