I'm selling this because I haven't used it, even though I received it many years ago. I couldn't confirm the control station's operation with the AC adapter. It started up for a moment, but then turned off. (Poor contact? Broken?) Perhaps someone who can fix it themselves, or maybe it will work if you replace the batteries. How about it? The rails are generally old. I stored them in a cool, dark place (in a closet). There is no box. How about using it to replenish parts? Please refrain from purchasing if you are overly concerned about details.
