Using a camera and mercury arc light, Southern's unique camera car photographs the outline of one of the many tunnels along Southern's lines. The beam of light, thrown out at a right angle from the track, is photographed by the camera. These photos are then analyzed to determine the size of the obstruction, and this information is fed into the railway's computer. Then, when Southern plans an oversized load along that route, the computer knows whether or not the shipment can be safely handled. For more information on this unique service to Southern's customers, see the article.
