Soundtraxx has announded and is beginning to ship the Micro Tsunami. Do not expect off the shelf availability until they ramp-up the production. Generally the Micro Tsunami is comparable the HO Tsunami except it's much smaller at 1"L x 0.5"W x 0.22"H. Here is an abbreviated/edited copy of their announcement.

INTRODUCING MICRO-TSUNAMI!

We are pleased to announce a new addition to our product line - the new TSU-750 Micro-Tsunami Digital Sound Decoder! This is the world's smallest 16-bit digital sound decoder! This full-featured decoder measures just 1" long x 0.5" wide x 0.22" and is rated for a 0.75 Amp motor stall current. This little decoder will easily fill your needs as a replacement for DSD-090 steam decoders - yes, it is smaller!

In short, the Micro-Tsunami has all the same powerful features you are used to in the TSU-1000 with only one exception - instead of four lighting outputs there are two. Big on features, small in size!

What's Available

We've listed the part number and the whistle selections here for your convenience. In addition to the whistles provided, each decoder also has many recordings unique to that prototype which may include the exhaust, airpump, dynamo, blower, bell and more. This means that in some cases you may see a whistle used on more than one decoder, since they were often used with different sizes and types of locomotives
