Abstract:
1. A detection system comprising: first sensing means, located adjacent a first rail of a railway, for detecting and communicating proximity along the first rail of a first wheel of a wheelset; and second sensing means, located adjacent a second rail of the railway, for detecting and communicating proximity along the second rail of a second wheel of the wheelset; wherein the first sensing means and the second sensing means are disposed along a common line generally perpendicular to at least one of a longitudinal axis of at least one of the first rail and the second rail and a tangent of at least one of the first rail and the second rail; wherein the first sensing means and the second sensing means are not strain gages; and wherein the first sensing means and the second sensing means are in communication with means for monitoring the first sensing means and the second sensing means; wherein data is produced by the first sensing means and data is produced by the second sensing means; and processing means wherein at least a portion of the data produced by the first sensing means and the second sensing means is utilized by the processing means to obtain at least one of a hunting condition, lateral position of the wheelset and an angle of attack.
