45:40 - September 2014 Bonus - DCC Decoded: 44-tonner sound (2014)

In this long-awaited DCC Decoded segment, Roger Chrysler installs a decoder and a speaker in a Bachmann Spectrum 45-ton locomotive in less than an hour.  Watching the entire process in real time should make it easy for anyone to follow along and get great results on their own.

Parts List for Bachmann 45-tonner:
Soundtraxx TSU-750 Micro-Tsunami Decoder, GE Cummins #827014
Soundtraxx speaker #810113, or ESU #50328


The audio quality of this video is fairly poor.  From about 28 minutes into the video it starts breaking up so badly that you cannot always tell what they are saying.  For what you are charging I would think that you could do a better job.  Not very professional IMHO.

Great episode, very informative.  (Edit: Sound quality was just fine for me)

Great video. Now I'm tempted to try this out on my Bachmann 44 Tonner. The sound was fine throughout the video.

I spot-checked the video and could hear no audio problems to the extent that are being reported.  Perhaps the site administrator Joe Fugate can help you if you are having persistent problems.

I would like to add that we would never knowingly post a video with severe audio issues.  In fact, this entire clinic was re-recorded (including a brand new loco and decoder) since the first taping was not up to my personal standards.

When you have issues like audio, keep in mind we work very hard to create good quality video. When you report an issue, please let us know what kind of device (PC, Mac, iPad, iPhone, Android tablet, or Android phone) you are using. Also, let us know which browser you're using (IE, Chrome, Firefox, Safari) and also let us know if the bad playback is occurring in both the main player and the alternate player.

As for troubleshooting you can do, try playing the video on more than one browser to see if the behavior persists. Since browsers are free, it' say good idea to have at least two so you can try different ones to see if the issue transcends browsers. Also try the video on more than one device, if possible. This will tell you whether or not the issue is related to your specific device.

Let us know some of your details and we'll see if we can pin down the issue. Do be aware that when we try the video, we find no bad audio problems.

Another good video and the sound was excellent as always and overall very professionally.done.  

Wow there is no way I would let this guy work on my equipment.  His soldering practices are extremely poor. Strip the wire with a soldering iron? If I ever caught any of my guys stripping wire with a soldering iron they would be headed back to school. I would think train masters tv would want to teach best practice to the new folks out there not hack work.


Soundtraxx wire is extremely soft and very fine. I showed how to nick the wire with my iron, then stripped it with my finger nails. If you use a stripper, there is the chance of breaking the fine wires or pulling it out of the harness as explained in the video.

I have been away from the hobby for over 20 years and back then, the electrical part of it was pretty straight forward.  Upon my return I've been confronted with DCC. I am fascinated and realize I've got a lot to learn. I loved this segment. Roger really helped me demystify some nagging questions, but I still don't think I ready to understand all the theory of what type of resistors or capacitors to use or when or where to use them.  Hey I admit it--- I'm electrically challenged, but I'm pretty good at changing light bulbs and knowinging how to plug my brand new NCE power station into the wall. I figured one of the best and easily understandable ways to really get into DCC is to convert some of my old "blue box" Athearn  locos from DC to DCC.  Has Roger and Trainmasters done a video on this topic? If not, would Trainmasters consider doing one or two segments showing Roger's step-by-step process to include a how to on choosing the right  decoder for the loco. I have looked extensively on the Internet and have found only one video that comes close to this idea, but after looking at the production quality and the thought that goes into a Trainmasters video, why should any of us electrically challenged DCC wannabes want to settle for second best?

I am critical of the camera work on this video.  Too many times fingers were between the work and the viewer.   Often the camera angles were poor.  Also, often the camera did not zero in for a close up view of critical work.  I know you fellas can do better!


The comment about the poor audio is indicative of a bandwidth issue on user's end.  Typically seen (or heard) with streaming video.  Also could be an audio driver issue on user computer.

On a separate note, perhaps using a foam cradle would help with keeping the fingers out of the way and provide a steady method of working on the engine.
