Abstract
A system for detecting stress in rails includes a railcar, having a rail temperature detector, and a rail imaging device oriented to produce images of rail joints and rail anchors. The imaging device and temperature detector are connected to a computer controller, which is programmed to provide an output signal indicative of estimated axial stress in the rail based upon rail temperature and the images of at least one of the rail joints and rail anchors.
