Prewar Lionel O Gauge Train Lines. 156 Engine + 610 & 612 Cars. This listing is for a rare Lionel prewar New York Central Lines engine No. 156 and 2 cars No. 610 – Pullman and 612 – Observation. The set appears to have been fully restored by a previous owner. The finish is EX/NM and the gold lettering has a few issues that can be seen in the photos. Particularly, the NYC markings appear to have been hand painted and some of the other lettering is in fair to good condition. However, the cars are undented, unscratched, and in outstanding condition. The engine was taken to a local train/hobby store, tested, and found to be in perfect working order.
