I'm still waiting for notification of my sound fitted 37043 being dispatched by AS. This is more stressfull than waiting for my better half to give birth (just don't tell her that 🤣). Steve

I noticed today that ESU now have a Class 55 Deltic sound file as a free download for the Loksound 5 decoder. Along with Classes 08/31/47/57. What a great development, and dare I say long overdue. Hopefully more classes to come. I wonder if the AS collaboration has been the catalyst? Steve

I remember that evening. I was in the middle of my commercial pilot course at Cranfield and was walking back from the local watering hole when I noticed the display. As someone who had seen many similar displays in Scotland I turned to my friends and said "there's the Northern Lights". They were a bunch of Southerners and all immediately dismissed the idea, how can it be as we're in Bedfordshire! Of course the headlines the next day showed I was correct. Steve

ESU uses CV31 & 32 as Index CVs, this way they can have many more effective CVs. A succinct explanation can be found here https://ncedcc.zendesk.com/hc/en-us/articles/210815663-Loksound-Indexed-CVs-CV8-151 If the CVs have been changed as indicated then whatever F29 did has now been moved to F2, and vice versa, which is what you asked for. I can't comment on whether this will actually give you the "brake function" you are after though. If you'd like to go back to the original decoder state and you didn't take a copy of the CV values you've changed just let me know. I can look up the original values and let you know what they are. Steve

Charlie above may be able to help with some specifics, but it would be really helpful if you can tell us which sound project you have installed on the Loksound 5. The issue probably isn't the decoder, but whoever programmed it, or perhaps last adjusted it. Have you tried a reset, as that may take it back to the settings the project designer intended. Simply write a value of 8 to CV8. Steve

To swap the current function mapping of F29 & F2 on the AS Class 37 decoder the following CVs should be changed: CV31 = 1, CV32 = 1 ---------------------- CV261 = 64 CV262 = 59 CV315 = 160 CV316 = 2 CV31 = 16, CV32 = 8 ---------------------- CV340 = 8 CV346 = 0 CV31 = 16, CV32 = 10 ---------------------- CV356 = 0 CV362 = 32 Steve

My neighbour has a white Tesla with the registration B787 FLY, which no doubt came with a big price tag. He's a pilot with Virgin 😉 Steve

@Hilux5972. Have a careful look at the removable bufferbeams, they are slightly different as only one has dimples to take the exhauster pipes. This caught me out initially as all three of my Deltics had the 'exhauster pipe capable' bufferbeams at the wrong end i.e. the #2 end. So I had to swap the bufferbeams over. Roy above has identified the #1 end for you. Steve

That'll likely be a limitation of your email provider. Upload the video to a suitable website and send AS a link? Steve

I've no idea what Accurascale have done to accommodate, but you can fit a either a standard coupling or Kadees as well as the one piece plough. Here's 37027 sporting a Kadee #18 fully seated in the NEM pocket, along with the 1-piece plough. I will be painting the connecting sprues black to better mask them at some point soon. I'll also be adding whatever pipework I can given this is my "coupling" end of the loco, so isn't strictly necessary.

And pronounced CAV - O - K I love hearing and seeing a smokey AN12. Pure magic!

They do.

Perhaps they just need to generate some cash? Could be lots of reasons, not all negative 😉

The Accurascale 37 does allow for both these options, and has to be one of the major advantages their model has over the Baccy one for those of us that like to fit all/most of the pipework and still have an option to fit ploughs. Steve

CV5 is setting the top speed, which for the AS 37 almost certainly doesn't need adjusting. As mentioned by @newbryford above, CV6 will be zero unless a complex speed curve is enabled (which AS haven't, by default). In order to get the thrash at slower speeds there seems like three obvious options. 1. Simply use the Drive Hold function (F7). The selected speed will remain and you can thrash away by increasing the throttle. 2. Use 'heavy train mode' (F5), which will slow acceleration (and see below). 2. Perhaps more elegant would be to permanently decrease the acceleration rate. CV3 is your goto here. This will slow acceleration whilst allowing the revs to respond to a more open throttle position. CV3 is defaulted to 40, but can be set to anything between 0 and 255 (the higher the number, the slower the acceleration). @PaulRhB has suggested on another thread using a value of 70. Steve

If you can indicate how you'd like the acceleration to be modified I can try and offer something that might help.

You will no doubt be disappointed to hear the car headlight brightness is already set to it's highest value (31), so I'm guessing the LED output is being moderated by a high value resistor. If you'd like to check use Index CVs CV31=16, CV32=0, then look at CVs 311 & 318. To change the markers you need to set Index CVs CV31=16 & CV32=0, then CV262 & CV270 with a value between 0 & 31. They are currently set at 5, so you have a lot of scope to increase these in brightness. Steve

Thanks Paul, I'll have a play! The 'brake key' is fun, just needs a bit of practice to get it right. I have a terminus, so not much room for error 😂 Apologies for the thread drift. Now back to discussions about an awesome layout. Steve

I agree, however this behaviour is baked into the sound project and can't be altered. I'm not convinced having it accelerate quicker after it sets off too quickly is the solution I'm after. The CV124 tweak at least allows for very slow speed movement, something that was highlighted earlier in this thread. There is a solution that doesn't involve any CV changes, but is a bit of a faff in my opinion. The Drive Hold function could be used before moving off i.e. Select F5, go to speed step 8 and the revs will increase ever so slightly, go back to speed step 1 and release F5. The loco will now move off nice and slowly. Another tool in the toolbox. Steve

The decoders are actually a LokSound 5 DCC, which is the version marketed in the US and Australia. No big deal, as the only tangible difference being the DCC version does not offer Marklin or Selectrix compatibility. The DCC version offers a '3 point' speed table as an option (which AS have used in the 37, but not in the 55!). On the more subtle end of differences they use different acceleration mutipliers. The root cause of the "delayed" start is the sound file, which can't be amended, in that the engine has been programmed to rev at speed point 8, which then triggers movement. By adjusting CV124, as described in my linked post, that connection is removed. I don't profess to being any sort of guru, so if you do find some other way of adjusting things that would be awesome. Steve

I've just posted on the AS Class 37 thread detailing a small change to the CVs that removes the problem of the loco moving off too quickly and only after reaching speed step 8. The change might not suit everyone, but I'm happy 😉 Steve

There's been mention of the AS sound fitted models not moving off until about speed step 8 when the sound is enabled, at least for the unrefurbished locos. This behaviour is matched by the engine revs not increasing until step 8, which in itself isn't a huge issue but it does mean that it's not possible to start with a crawl. I've been trying to find an easy solution, and the best I can come up with involves amending only one CV. If you change CV124 = 0, then this behaviour is no longer a problem. (Note, to undo the change simply return it to its original value: CV124 = 4) On my model I've also been able to reduce the starting voltage, and therefore have a slower speed step one crawl speed. Simply amend CV2 = 2. (Original value CV2 = 3) I've made a very amatuerish video to demonstrate the difference. Please excuse the 'dining table toy train loop', as I though I might need a roundy roundy for the demo. Steve

That echoes my experience exactly. I think the 'delay' in moving might be tied to the sound project, given it crawls beautifully on speed step 1 when the sound is off. With sound on, the initial notch up will cause the break release sound to trigger, but no movement until 8 (assuming 128 speed steps) when a small increase in revs happens and off she goes. I'm going to see if there's some way of changing the behaviour by modifying CVs, but if it is baked into the sound project I suspect there won't be. Steve

I'm not aware of any other manufacturer of a DCC ready loco that provides comprehensive details, mainly because most of the configuration needed is decoder specific. Of course I could be wrong. To list all info needed for any type of decoder fit would simply be an impossible task I suggest. Whilst feedback allows for improvement, it does need to be couched in the correct manner for the message to be listened to and possibly acted upon. And we're all allowed our opinion, but the same principle applies!

AS provide a fully programmed drop in decoder, something no other manufacturer does as far as I am aware. If you choose to go off piste, I suggest you can't really then complain. If you found it "unnecessarily complicated" did you reach out to AS for any assistance regarding which lights are wired/mapped to which output? If you did I'm sure the answers would have been forthcoming. Steve
