Finally, Some Sound

The Number 19 at Orford Junction.
Like everyone, I work on a project for a while, get tired of it, quit, and, hopefully, get back to it some time later. A couple of years ago, I refitted almost all of my locomotives with Tsunami sound decoders. By the time I had finished most of them, I got tired of the project and left two locos silent and running with only non-sound decoders. Over the last couple of days, I finally decided to remedy that situation and install the sound decoders.
The speaker can barely be seen at the left rear corner of the tender. A Sagami 16x30 motor  was used.
Some of the tender frame had to be removed to allow the decoder to fit.
   The two engines in need were No. 19, a Pacific Fast Mail import of the V&T Reno. This engine is a 4-4-0 with the motor, decoder and speaker in the tender. There is precious little room for all these things, so little in fact, that I had to skew the motor slightly to allow the Tsunami to fit. Many people think that a motor in the tender will result in "tender wobble" as the loco runs. This is not the case. If a rubber tube coupling is used between the engine and motor, you can expect the wobble but not if Northwest Short Line U-joints are used. The drive shaft between the engine and tender is not real noticeable and there is more room in the engine for weight which means long trains. My 4-4-0s pull 10-12 normal-sized cars without a problem.
   The speaker I used was a Soundtraxx 3/8" speaker. It's not real big but it does put out the necessary sound and it's the only one that I can get to fit. It's located at the extreme rear of the tender behind the flywheel.
The motor is attached to the tender shell. Screws are covered by the wood load.
The Number 16 at Stockton. It is still lettered for the MSN but the tender will be repainted and relettered for the Stockton & Copperopolis.
   The other engine was No. 16, the Stockton switcher. It had a small Lenz decoder in it which gave good results but no sound. Another Tsunami went in here. There was enough room to add a big larger rectangular speaker I had. Everything was a tight fit due to the slope of the tender deck but it now works well and will please the Stockton yardmaster who was complaining about having an engine without sound.


  1. Don,
    Wow,I hope you are willing to share how you put the sound into the MEW 0-6-0. I have two of these beauties and they form the basic power for my Sahwatch Street Yards. I have not heard of anyone successfully putting sound in one these.

  2. Nice job of squeezing all that gear in the locos.

  3. The trackplan in MR named after this engine (or vice versa) was a fun track plan.
