Checked out Ebay and the pictures are evidently already gone. While I'm no authority on the SVRy, I thought I'd correct one thing on this post, the mention of a Plymouth. The SVRy had #100, a Whicomb gas mechanical used from 1930 to 37 and recently donated back to us by JR Simplot Co. Replacing this switch engine was the 101 Davenport diesel mechanical which was used from 37 to 61. This is probably what is in the picture on Ebay as it would have been in service at the same time as the 250 and 251. The 101 is at CRRM.
