Model Railroader Magazine is starting a new series in January about building a small HO layout based on the prototype coal hauling Virgina RR. In the introductory video on-line was a fold-up section that had a very interesting digital display on it. It turns out that it is an operating digital weigh scale called WeighScale. It uses a Walther's scale house on the top of the layout with a gauntlet track and infrared light. The display is available in either a digital or meter version. Installation seems rather simple and straightforward with the hardest part building the gauntlet track. The retail price is $89.95 or about the same cost as a sound decoder. Here is the link: http://bouldercreekengineering.com/weighstation.php With my modest railroad producing grain, cement, and limestone shipments, this will be a must have addition.
