After 30 years of business - serving the model railroad hobby - as of mid-December 2019, Railway Design Associates has sold the business rights to Rail-Scale-Models. This includes rights to design and production of all RDA products and detail items. Rail-Scale-Models provides structure kits and laser-cut detail parts in all scales, and is excited to add the RDA product line to their catalog. They will release products on their website - Thanks to all of our many customers over the years.
