I am in the process of modeling the Bethlehem Steel Lehigh Plant in "O" and currently working the design of the Hoover Mason high line and associated cars, which delivered ore, lime stone and coke to the blast furnaces. I seem to remember an article a while back in one of the train magazines, which discussed an approach for a kit-bashed Hoover Mason Trestle Car from a Lionel post war 55 Tie-Jector motorized unit. Does anyone remember this article and the magazine in which it appeared? While I've scanned the digital versions of the O gauge and tinplate magazines, I haven't been able to find the article. Any help you can provide or thoughts you may have on have concerning my project . I have attached photos of the prototype for reference.
