ABSTRACT:
A method and apparatus for rail seat abrasion measurement and analysis is shown wherein a rail seat measurement device is mounted with reference to non-wear portions of a concrete railroad tie and includes linear potentiometer devices adapted to determine a spacial relationship between the body of the measurement device and wearing portions of the rail seat. In this manner, the measurement device may be consistently mounted upon the non-wear portions of the concrete railroad tie in order that a series of accurate abrasion measurements may be taken. Other information collected includes static information such as track curvature, bank, and grade and dynamic information such as loading conditions and environmental conditions to which the rail seat is exposed between abrasion measurements.
