CNR 86 – Full Throttle – 2nd Run

I’ve made some more adjustments to the Loksound decoder in CNR mogul 86 and CNR 10-wheeler 1560, which are loaded with Full Throttle Steam packages from ESU. And therefore, I’ve made a follow-up to yesterday’s video… this time focussing on 86 in action on my layout…

In this video, I’ve highlighted a number of sounds generated by the decoder. Some are automatic, some are user-controlled, some are both. The video features braking noises, the air compressor, bell, whistle, injectors and dynamo.

In the first scene, the locomotive drifts into St. Williams. In the next, it works hard to start the train out of St. Williams (with Full Throttle’s “Heavy Load” function engaged). Finally, the engineer drifts over a bridge in the Lynn Valley (with Full Throttle’s “Coast” function engaged), before opening the throttle to build speed for the run into Port Rowan.

I still have some minor tweaking to do – notably, to adjust volume levels – but I’d say I’m 98% of the way there. Colour me impressed!

  1. Wow, the new ESU full throttle steam sounds and running characteristics are extremely realistic and bring your excellent modeling truly to life!
    I really enjoy the full throttle diesel decoders on my layout and have fun tweaking their performance with the ESU programmer, but the steam, my my, maybe I need some steam.
    Thanks for the videos.
    Cheers, Joe Smith

  2. Well, I guess I just joined the group who will be looking to add a steam locomotive or two to my roster! This electronic stuff is getting expensive, but just so much fun!

  3. Impressive sound throttle. How does the quilling effect work? Is it one of three settings , random, or playable?

    Now I have to see if ESU has one for a heavy three truck Shay.


    • If you don’t have a playable throttle, it’s a random pull of the whistle cord. I don’t know how many different pulls are recorded on the decoder, but it works well. And the whistle does run as long as you hold the button down – as one would expect. If you DO have a playable throttle, you can take that random pull and modify the pitch.

  4. Trevor, the “Heavy Load” is interesting, but can you describe how that works (or not) in conjunction with gradually increasing speed? You mentioned in the last post that momentum would influence the exhaust note, but can the “playable” exhaust note also be used in an acceleration case?
    I like the *idea* behind TCS’s automatic load sensing, but as we discussed, my locomotives slip before WowSound decoders detect much load, keeping the exhaust note increase more subtle than I would prefer. Perhaps that can be tweaked, perhaps not, or perhaps ESU’s approach is a better answer.

    • Sure thing, Matt:
      I’m new to Full Throttle, but there’s a setting in the LokProgrammer that suggests Heavy Load tells the decoder to behave – sound-wise – as if the throttle is set higher than it actually is. Therefore, it generates a stronger, sharper exhaust note.
      The “Heavy Load” sound setting is adjustable (although I haven’t adjusted it). Presumably, one can make the exhaust note even stronger – which would solve the issue you experienced with your TCS decoders.
      If I leave the motor lock engaged, then the Heavy Load sound would be playable – one could set a given speed, then wind up the throttle to create a strong exhaust note, or back off the throttle to soften it (or eliminate it entirely and drift). Some may prefer that – but for my layout, where all trains are short and the RoW profile is gentle – I would likely only need the Heavy Load feature for the first couple hundred (scale) feet when starting from a standstill – and I am confident that can be addressed by increasing the value in the “Heavy Load” setting.
      Does that answer your question?

      • Since recording this video, I’ve actually made further adjustments (to which I’ve alluded in my previous reply).
        I’ve boosted the acceleration value (CV3) to around 180 (IIRC). And I’ve turned off the motor speed locking feature on the “Heavy Load” function. I have left it active on the “Coast” function, however.
        This lets me turn on Heavy Load before starting the locomotive, then wind out the throttle to produce a strong exhaust note.
        As I approach the speed I want, I back off the throttle then turn off “Heavy Load”, and the chuff modifies to become softer.
        With the train moving comfortably, I can engage the “Coast” function and the chuff will fade away as the locomotive drifts. The throttle knob at this time can be turned to zero without affecting the speed.
        When it’s time to stop, I turn off the “Coast” function and the locomotive slows to a stop, with appropriate brake noises.

        • Yes, that helps. After reading your answers, it appears I misused the term “Heavy Load” initially – I thought it was the same as “motor lock”. Questions are hard to answer when definitions aren’t locked down!
          That said, your answers both clarified the terminology and answered my question; momentum will provide the stronger exhaust note *while accelerating* (with appropriate throttle fiddling). That sounds similar to TCS and even the early Tsunamis I have, while motor lock would allow me to “play” the exhaust note to be louder at a sustained speed – such as climbing a grade. That would be a useful tool.
          It sounds like you’re starting to settle on a configuration that keeps the number of button presses to a minimum.

          • Hi Matt:
            Glad it helps.
            Full Throttle Steam offers a couple of options for getting the sound you want – Heavy Load (and/or Coast) can be used with or without locking the motor to a given speed. Which combination you use will depend on the layout you’ve built.
            For my layout, which is flat and primarily involves switching, it makes sense to not lock the motor when using Heavy Load. But someone who has a layout designed for mainline running over a line with grades – a mountain, helper district for example – might want to use it with the motor lock feature. That would allow the locomotive(s) to use BEMF to maintain a consistent speed, while the operator varies the sound to represent going up or down hill as required.
            While that requires more experimenting on the part of the end user, LokProgrammer makes it as easy as clicking a check-box – and it’s great to have the choice.

    • Hi Michael:

      Thank you – and “not yet”. I’ve now have two locomotives with LokSound decoders and Full Throttle Steam installed: CNR mogul 86 and CNR 10-wheeler 1560. The rest of the steam fleet is equipped with WOWSound, but based on my results I will start buying LokSound decoders and replace them.

      I also have LokSound decoders in CNR 15815 – my gas electric – and in CNR #1 – my GE 44 Tonner. They do not – yet – have Full Throttle Diesel installed: I only recently set up my LokProgrammer, and ESU has not yet updated the GE 44 Tonner sound file to Full Throttle features. When they do, I’ll update the decoders.

      Meantime, I have some non-LokSound decoders in other pieces of equipment – including my CNR RS18 and my Burro Crane. I will replace these in time as well. The RS18 will be easy – ESU already offers Full Throttle Diesel files for the ALCo 251 prime mover used in these models. Currently, the Burro does not have sound – but with a LokSound Select Micro decoder and the surprisingly good audio produced by mobile phone-style speakers such as ESU’s 50321 (just 15mm x 11mm) , that could change.


  5. Are you using LokProgrmmer for your tuning, this is the one thing holding me back from investing. I can just about fine tune using JMRI. I guess the investment is worth it as it opens up the way to future proof any ESU decoders.

    • Yes I am! This is my first experience using LokProgrammer and I’m enjoying it.
      It’s essential if you want to download your own sounds. But those looking to upgrade the sound on existing ESU decoders to Full Throttle Steam may have a local hobby shop that can do it for a small fee. I have two in my area that will.
      As for setting CVs, I’ve done that without a LokProgrammer in the past. I have no experience with JMRI and ESU decoders but I assume CVs on a LokSound decoder can be adjusted using JMRI…

  6. Howdy again! You mentioned above: “When it’s time to stop, I turn off the “Coast” function and the locomotive slows to a stop, with appropriate brake noises.” Have you used the independent brake at all to stop, or do you always coast to a stop? (heh, turning off the “coast” function – need more words! :^)

    I’m using the unmodified Soo Line FT steam sound package to start (Select, not v4) and using the brake doesn’t emit any brake sound – just coasting to a stop does though.
