Air Conditioning Company Detail
A heavyweight car is one that is physically heavier than a lightweight car due to its construction. While early cars used wood construction, Pullman switched to heavyweight riveted steel construction in 1910, more or less at the same time as other rail car manufacturers. Heavyweights are said[by whom?] to offer a more luxurious ride due to their added mass (from the plate steel construction and concrete floor) and, usually, six-wheeled trucks (bogies).
In the early 20th century, air conditioning was added to heavyweight cars for the first time. An air conditioned heavyweight car could be spotted easily since the area where the roof vent windows existed was now covered, either partially or in full, by the AC duct. As lightweight cars were introduced, many heavyweight cars were repurposed into maintenance of way service by the railroads that owned them.
