Device to Capture High Resolution Images of the Underside of a Freight Car Traveling at Full Speed
20220377251 · 2022-11-24 ·

A plurality of cameras is secured to railroad ties to take high resolution images of the underside of a train car as it passes over this plurality of cameras. These images are important to insure the structural integrity of the parts of the rail car as well as the connection means—a coupler and pin—between two rail cars. The shutter speed of the cameras is determined by the speed of the train as it passes over the cameras. As the images are taken, the images can be downloaded and sent to a remote location for further analysis.
