SoundTraxx Sound Decoders for Your Locomotives

Tsunami2, Econami, and familiar locomotive sounds

A diesel idling at the station sounds a lot different from one pulling a train uphill. SoundTraxx decoders bring those changes to a model railroad, along with bells, horns, whistles, and lighting effects. They are especially popular with modelers upgrading older locomotives or getting more out of a DCC-equipped roster.

When you shop SoundTraxx at Trainz, you may find decoders, speakers, and related components for a new installation or an older engine that needs attention. Check the part number and locomotive requirements before choosing a replacement.

Tsunami2 and Econami: Which SoundTraxx Line Fits?

Different options for sound, control, and installation

Tsunami and Tsunami2

The Tsunami family is well known for detailed steam and diesel sound. Tsunami2 adds a broad range of programmable sound and control features, making it a popular choice for modelers who like to fine-tune how a locomotive sounds and operates.

Econami Sound Decoders

Econami gives modelers SoundTraxx sound and DCC control with a more streamlined feature set. It can be a practical choice when you want sound in a working locomotive without all the extra options found in Tsunami2.

Speakers, Lighting, and Installation Parts

A sound installation may also call for a suitable speaker, wiring, and other small components. For replacement items beyond the decoder itself, Trainz also carries electrical and electronic train parts.

Finding SoundTraxx Parts at Trainz

New, older, and hard-to-find decoder versions

Match the Decoder to the Engine

Look at the available space, motor current, DCC system, speaker requirements, and whether the locomotive already has a decoder socket. A SoundTraxx decoder for one engine is not automatically the right fit for another.

Older SoundTraxx Releases

Some modelers are after a particular Tsunami or Econami part number to keep an existing locomotive running. Trainz inventory can include older, pre-owned, discontinued, and new old stock electronics as they become available.

A Little SoundTraxx Background

How sound became part of everyday model railroading

SoundTraxx helped make onboard locomotive sound a practical upgrade for model railroaders. Its Tsunami sound decoder line became especially familiar to steam and diesel modelers, and later Tsunami2 and Econami products gave hobbyists more ways to add sound and control to their engines.

Today, SoundTraxx remains associated with locomotive sound, DCC decoders, and the supporting electronics used in model railroad installations. Whether you are upgrading one favorite engine or working through an entire roster, the right decoder can make an operating session a lot more enjoyable.
