G Scale Train Locomotive and Tender Kalamazoo Train Company 1/24 scale in box. I pulled it out of storage and tested it. It ran very smooth forwards and backward low throttle to high throttle. All speeds ran very smoothly. It has some dust from long-term storage.
This locomotive was made by the Kalamazoo Toy Train Company. This company is now Hartford Train Company. In fact, Hartford uses the same chassis and bodies on their new products. It is based on 1/24 scale Narrow Gauge using standard G scale track and power.
These are getting very hard to find, especially in original boxes!
