Reinder Feenstra

Reinder Feenstra is an independent Dutch developer whose single, tightly-focused catalog centers on Traintastic, an open-source application that turns an ordinary Windows PC into a digital command station for model railroads. Designed for hobbyists who run DCC- or Marklin-digital layouts, the program combines real-time throttle control, block detection, route setting, and automated scheduling within one uniform interface. Users can draw a schematic of their track plan, assign locomotive decoders, define occupancy sections, and then operate everything manually from a virtual dispatcher desk or let the built-in automatic mode run timetabled trains while it respects signals and interlockings. Because the project adheres to the S-88, LocoNet, and OpenDCC standards, it interfaces cleanly with off-the-shelf command stations, booster modules, and feedback sensors, so existing club or home installations can migrate without replacing hardware. Layout data is stored in portable JSON files, making it easy to exchange plans or back up years of fine-tuned automation logic. Feenstra releases iterative builds that add new protocols, refine the path-finding engine, and expand language packs, all under a permissive GPL license that encourages community contributions. Traintastic is available free of charge on get.nero.com, where it is delivered through winget and other trusted Windows package sources, always installing the newest official build and supporting batch deployment alongside additional applications.
