For Sale is my MTH MT- 4007 Santa Fe Green Madison 5 passenger car set in excellent condition and with its original box. They run on O-42 and are 18" long big boys. Lighted interiors with people silhouettes.Set is in excellent condition and it appears to me that it has very little if any track time before I bought them. I have never ran them just need more room in the basement! One of the cars has some light marks on the light roller. Good Luck and thanks for looking!
