A few weeks back, I started writing about modeling a Santa Fe Bx-57 PS-1 box car. One of the necessary changes was to replace the Apex Tri-Lok running board with one of the new Kadee U.S. Gypsum Expanded Metal running boards. The photo above shows this new running board. It is spectacular. It captures the lacy look of this style of open grid running board. It suffices to say that Kadee has done it again. Note the board as shown here looks greyish because it was blasted with aluminum oxide, but not yet cleaned. I will post the details on the finished model very soon.
