Take full control of your model locomotives with the ESU LokSound Programmer. This powerful tool lets you customize, update, and fine-tune your ESU LokSound and digital decoders with ease—no manual CV entry required. Simply connect the programmer between your PC and a programming track to read, edit, or upload settings using the included software.

You can adjust locomotive addresses, lighting effects, acceleration curves, and sound profiles with a few clicks, or even replace and rearrange individual sounds like whistles or horns. The LokSound Programmer also supports firmware updates and works with all ESU decoders, including DCC, Multiprotocol, and mfx models.

Each set includes the LokProgrammer unit, power supply, serial cable, USB adapter, software CD, and manual—everything you need to get started programming and personalizing your fleet.
