Freight Car Friday - TCIZ 400321

How did a highway trailer make it into Freight Car Friday? Well this isn't your everyday truck trailer.

TCIZ 400321
TCIZ 400321 is still in intermodal service, if not in Roadrailer trains any more.

TCIZ 400321 was built as a dual mode RoadRailer - a truck that could ride the rails with the simple addition of a set of railroad wheels. Among the advantages of this technology was the efficiency gained through not needing any railcar to carry the shipment. Trailers and containers however do generally have a much shorter lifespan than a rail car. And the Roadrailers are no exception.

Triple Crown (owned by Norfolk Southern) is getting a few more years of life out of some of its older Roadrailers however. Although this trailer is no longer allowed in Roadrailer trains, it is still a perfectly good highway trailer. So it rides the rails on flatcars and spine cars like its cousins. It's the next, and hopefully not the final, chapter in the history of this interesting operation.
