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 sound gimmick rails are partially 3D printed. There are no problems with the operation. The standard set includes a railroad crossing, a car wash, and a station gimmick rail, but this set also includes a bridge, a tunnel, and a 60th-anniversary set of gimmick rails. To ensure a smooth transaction, please feel free to comment if you have any questions 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 shipping" function to consult with me. I will almost always accept requests, except for manual price input. Please also take a look at my profile. For those interested, please see below. Here's the work that was done: ★ Removal and cleaning of dust, hair, etc., around the wheels and motor unit of the power car. Some parts may not be completely removed. ★ Independent maintenance of the motor. Restoring the motor to its original condition. Since I haven't replaced it with an aftermarket motor, you may be able to request repairs from the manufacturer. They won't accept modified items. ★ Cleaning of the exterior using various cleaners. The above is the maintenance content. I haven't done anything more than that. I hope we have a good relationship m(_ _)m
