ON THE COVER
"Echoscoping" a freight car axle journal with ultrasonic waves-another of the modern ways that help Southern Railway serve the modern South.
Hidden defects don't stay hidden from this electronic device used by car inspectors in Southern's yards.
And it is only one of a complete set of inspection and repair tools and parts carried on this sled-type crawler used along inspection tracks to make sure that outbound freight trains are ready for the road.
