Athearn HO 65' Mill Gondola, CSX #490590 Overview
First built by General American in the early 1940's, the mill gondola was designed for steel mill shipments that required extra length and versatility. The sturdy riveted construction could carry the necessary weight plus both end panels were hinged to fold inward. This allowed long beams and other extra-length loads to extend beyond the length of the car. When carrying such loads, the mill gondola requires flat cars coupled to both ends to allow clearance of the overhanging load.
