In August 2007, I found Vintage Locomotives, Inc. (VILX) Alco RS3 512 sitting at the Southern Appalachia Railway Museum in Oak Ridge, Tennessee. She was built as Reading Railroad (RDG) 495 in 1952, to United Railway Supply Co.(URS) 495, to the rather wordy Oglebay Norton Industrial Sands Incorporated (ONSX) 512.
