: Users download these .rar files and extract them to find a .esux (or similar) project file. This project is then opened in the LokProgrammer software to be tweaked (volume levels, function mapping) and finally uploaded to the locomotive's decoder via a physical programmer track. Important Notes for Users If you are using a LokSound 5 decoder,
