Truck Performance Detector (TPD)

The objective of TPD System is to detect & remove poorly tracking cars (curving & tangent performance). TPD systems identify railcar truck suspension systems that do not perform optimally in curves. Poor performance results in derailments due to wheel climb, gauge spreading, rail roll over and panel shift. Poor performance also contributes to wear on track, wear on wheel profile and flanges and rail. TPD Systems also is able to indicate poor bogie performance by measuring Vertical Force & Lateral Force. Derivatives of the vertical and lateral are used to assess the curving performance of the bogie.
