Through the Lynn Valley

Another day, another video of one of my CNR moguls equipped with Full Throttle Steam – the new sound packages soon to be released by ESU for their Loksound Select and Loksound V4.0 decoders.

I’ve spent a little more time running the locomotive and I’m getting much more comfortable using the Heavy Load and Coast features to bring the sound to life.

As I’ve mentioned in previous posts, these are beta sound files. The production versions should be released soon. Watch the ESU/Loksound USA website for details.

Meantime, I’m getting ready to replace decoders in more locomotives. It’s a great time to be modelling steam!

  1. Very nice Trevor — thanks for sharing.

    Not sure whether you need to join the sound tech union or the locomotive engineers but either way you seem to be well qualified!


  2. Hi Trevor. I really like where Lok Sound is going with the steam sounds and operations. I notice what sounded like the cylinder drain cocks being opened after about 7 revolutions of the drivers to let out built up condensation. This Is not prototypical as the cocks should be opened before the engine starts to move and closed after about 7 revolutions. This lets the built up condensation out of the cylinders. As water will not compress there is risk of blowing the ends out of the cylinders if the water is not drained out at startup. Looking forward to installing these new decoders in my steamers.

    • Hi Ken:
      Actually, I think what you’re hearing is either a change in the exhaust note as the locomotive starts working harder to start the train, or the injectors – not the cylinder drains.
      I have not posted a video with the cylinder drain cocks open.
      The Full Throttle Steam files include cylinder drain cocks and they can be set up as an automatic feature and/or as a manual one. I have not set them up manually. On automatic, they do not open every time the locomotive starts up: They run on a timer so the locomotive has to be stopped for a certain length of time before they are active.
      The injectors are one of the randomly-generated sounds, like the air pump. While I have it set to automatic/random right now, I will probably move that over to manual operation and assign a function key. If I was behind the throttle, I would be mad at my fireman for opening the injectors when I’m trying to start a train, since doing so drops the steam pressure as cold water hits the boiler. The fireman should’ve been running the injectors while the train was stopped, to give the boiler a chance to return to temperature.
      I worked as a fireman’s apprentice for a couple of long weekends at the Maine Narrow Gauge RR & Museum several years ago. That experience taught me a lot about how steam engines work and when I got home, I reprogrammed many of my sound decoders as a result. At the time, the decoders I was using did not have the cylinder drain feature and that was a key reason that I replaced the decoders.

    Looks and sounds great! Thanks for sharing.
    From one operator to another, what is your plan for training guest operators to run your equipment? Or are you going to reset everything to operate the “old” way – stop and go with throttle knob control?

    • Yes, I tweaked it. I followed the instructions in ESU’s decoder manual. The settings will be different for every class of engine – and sometimes, for each engine within the class. The first one took a couple of hours to do – the next ones went faster as I became more familiar with the process.
      If I recall, I performed ESU’s automatic Back EMF adjustment first.
      Then, I set up the momentum and speed curve – and once all that is done, I start messing with the chuff synch values.
