Summary
[edit]
| Description | The test cars were also used to calibrate other industrial railroad scales whenever the NBS schedule permitted. A total test load of 80,000 pounds was carried by each car. This consisted of 7 ten thousand-pound weights, 3 of which were mounted on the small truck (right), and the truck itself, which was adjusted to weigh exactly 10,000 pounds. Auxiliary equipment was carried on the car for proper handling of the test weights. | |||
