Canadian National. Cab #3616 All trains are from the Dwayne Martin Estate from Gouverneur, NY. He was an avid lifetime collector of "O" gauge trains and spent much of his freetime traveling across the Northeast attending model train shows. Some of the trains are new in the box, many are used and put back into the original boxes and some are used and sold without the box. All trains are sold as is and we have not tested any of the locomotives.
