The first mention of thawing sheds in the N&W Annual Reports is in the 1951 Annual Report which states that the sheds were installed in that year for Lamberts Point Pier 4 (now long gone). The 1962 Annual Report states that thawing sheds accommodating 16 cars were provided for the then new Pier 6.

The N&W thawing sheds were designed to minimize damage to the hopper cars by using convection heating (controlled low flames below the cars) or infra-red radiant heating. Some customers' unloading facilities were not so considerate. I remember hearing about a steel mill in Ohio that would build roaring fires under the cars, damaging steel sheets and particularly destroying journal bearings, brake slack adjusters, air brake valves. etc.

There was a plant west of South Point that barbequed hoppers, and Portsmouth shop had to get them
back in shape. But about the Pier 6 thaw shed -- I wonder if NS's new aluminum hoppers are verbotten ?
