Sound decoders

Zimo Sound decoders

Zimo sound decoders are known for their ease of use and with a Roco Z21 and a computer (Windows, though works through Parallels with a Mac), you can actually upload new sounds to the decoder. No additional hardware necessary! The Tramfabriek will only sell the tiniest decoders, mostly suitable for N and 009/H0e/H0m gauge.


Pre-installed sound

If you would like to have a certain sound installed,  the Tramfabriek can install a sound from the Tramfabriek Sound Experience. The Tramfabriek does NOT install 3rd party sounds that need a paid unlock code! Check for available Zimo sounds here on the Zimo website.

Tramfabriek Sound Experience files are free and installed, when chosen, with the purchase of a decoder. Choose the sound you would like to have installed in the pop up window. If you choose a sound from the Zimo database, specify which one in the notes at the check out.
