TRAIN ACTION MEASUREMENTS IN THE TROPICANA UNIT TRAIN

The extensive test program conducted with the Tropicana unit train operation has led to a better understanding of train dynamics, train handling procedures, and the required in-train characteristics of hydraulic end-of-car units. Results of the test with a conventional gear train containng a group of 100-ton cars have shown the presence of train action forces in the 300,000- to 400,000-lb range. The magnitude of train action forces are dependent to a large degree upon individual car weights. As the car weights increase, the dynamic force levels increase.
