This paper describes recent manufacturing modernization efforts and technical
progress at the production facility of wrought railroad wheel and axle manufacture.
Improvements to forging and rolling processes are discussed,with special emphasis on the
new computer-controlled, vertical wheel rolling mill. Also described are upgrades to
forging and dishing presses, the rotary heating furnace, automated wheel
stamping equipment and a hot in-process laser inspection system. Finally,
the installation of a new phased array ultrasonic inspection system for wheels is
