It is called modelling - ancient, long-lost craft, sadly!

 

CJI.

I don't consider modelling a lost craft at all but it has in many ways evolved, for example from scratch-building a wagon from bits of plastic to spending hours designing the same wagon in CAD to 3D print on a home printer. In the case of these wagons I would content there is little point in modifying Farish ones to take an NEM pocket if others are available (and cheaper) that already have them.

Nope, as I need some NEM fitted wagons for shunting if I want to save myself having to cut couplings off Farish wagons.

That would go for me too, subject to (as I suspect) the Vanfit looking perfectly fine in normal BR bauxite I will certainly be buying a few, and some of the Iron ore tipplers too. 

Personally I don't think the horrible "Santa" livery including different colours on the solebar helps and I will wait until I see the Vanfit in "proper" BR liveries before reaching any conclusions, but it appears the RRPs will be somewhat less than the Farish models and it does have NEM coupling pockets which Farish vans and mineral wagons do not currently.

i got a replacement one now, seem to run ok and less wobble, need to run it in some more.

Sadly I have to agree, I would imagine the green ones will sell well enough, but the other liveries I am not sure about. The sound upgrade has been "in the works" a while and for me it has always been surprising that Bachmann would prioritise this over things like the Class 37 and for steam the Duchess/WD Austerity as far as a sound is concerned.

Don't aquire steamers very often but really tempted by a sound 2mt. A combination of it being 46464 which I'm sure pulled my train on a childhood visit to the Strathspey plus the minitix one being my starter loco in N at a similar time may be to overwhelming from a nostalgia perspective.

 

Rob

I have one of the new sound fitted Ivatt 2MTs (in my case 46447 as I remember it pre-restoration at Quainton Railway Centre). I am really pleased with it, the addition of sound was certainly a worthwhile enhancement and I think the Bachmann sound-file is excellent.  Given the cost of a Zimo Next 18 sound chip is in the region of £110 on it's own, I actually think that especially at a discounted price of typically a tad under £230 the sound fitted model is excellent value too.

Perhaps Spring 2023 will bring both along with some more class 47 liveries? Along with new liveries on the likes of the class 37 and 90. Surely the 37 has to be next for a Next18 upgrade?

 

SB

I would hope more 47 liveries will follow, especially earlier ones, and I absolutely agree that the 37 with it's long life and huge range of variations in detail and liveries simply has to be high on the list.

Roy

I had hoped (but not expected) that given the length of time since that last all new tool steam loco was released we might have seen something new in that respect to round off 2023, but on the plus side there is still a good volume of N coming through which is a big improvement on where things were not so long ago. As has been said elsewhere the Class 47 sound upgrade has been expected for some time, so isn't a huge surprise, but it would have been good to see the popular early BR two-tone green with small panel and BR blue (pre or post-TOPS) included rather than just more modern liveries.

The military liveried EFE J94s were nice to see, and had they appeared in the initial run I would have chosen one of those as an initial purchase but having already purchased two, another would be a bit of an indulgence, however I am tempted as they are lovely little models.

The phrase "nothing for me here" does spring to mind, but I haven't done too badly this year in terms of new items so I can say that without any huge element of disappointment this time.

As I said to Simon K a year ago, I think they should go for pre grouping locos which survived well into nationalisation to get the most choice of livery/era. Especially those which ended up quite widely distributed.

A Midland 0-4-4T or LNW 0-6-2T, say. Not sure what the Southern, Western or Eastern equivalents would be.

 

Some of the Great Central types would also fit with this idea, I am thinking J11 and ROD 2-8-0 in particular, but I would not expect such a "policy" to be adopted as there would be also quite a risk attached. Good sellers in the OO range would probably be where the process of deciding on further new locos would start from including steam, I would expect them to continue to be looking more towards "low risk" models for the next phases, including prototypes from the "Railroad" range i.e. stalwarts like the GW Large Prairie, 4F 0-6-0, Jinty etc. However any of that is a long way off and does make assumptions based on what "modellers" would probably like to see - we have already been told that the traditional "modeller" is not Hornby's primary target, so they may make entirely different marketing/sales assumptions and choose entirely different locos as a priority - things like the FLIRT.

Pop a SugarCube8 speaker above the PCB part and it fits really nicely (not wired up here, but at least shows the position).

 

It just didn't occur to me to put it there, the uncluttered space above the weight lured me in🤔!

Having followed John YouChoos suggestion above, I set to it and dismantled the chassis to get to the installed speaker which is tucked under the PCB. I was surprised when I removed it to find that there is no kind of resonance chamber attached, it just sits diaphragm side down in the chassis, "sealed" to that by some tacky "stuff" and sound emits (notionally anyway) through holes in the bottom of the chassis. Below is a picture of the speaker I removed in the foreground, together with the Sugarcube I replaced it with behind (complete with such a chamber as will be noted).

The second picture shows the new speaker installed by soldering speaker wires to the contact tabs on the underside of the PCB, I routed the wires up through the aperture in the PCB where the rear of the motor is and thus to the speaker terminals. The speaker sits very nicely on the traction-weight as can be seen. However this is not how it ended up because Klutz as I am I failed to allow for one of the stiffeners in the roof of the Unit so the body wouldn't go on over the speaker!  I therefore extended the wires and relocated the speaker immediately behind the cab-bulkhead and this time everything was fine 🙂 - forgive me not taking another picture but I am now too busy running it!

Having tested the new setup, with the Zimo chip at default settings there is no "crackle" whatsoever and it runs and sounds very nice even without the body on, and once that is in place the sound is even better.

As has been said by a few people it is the loco body that provides much of the amplification rather than anything else which is indeed fortunate. However by way of what I hope is received as constructive feedback, I would implore Revolution Trains to look again at the chassis design for the 120, because with seating units in place the benefit of the body as such a sound chamber will to a large extent be lost. It would seem perfectly feasible (for example) to install a better and beefier speaker with sound-enclosure above the chassis in the guard's compartment without any visual impact.

I am going to leave it there, I am not encouraging anyone else to do as I have done, but for me it has provided what I consider to be a proper "fix" that doesn't need to compromise on the sound's volume and as the model is in every other respect exquisite I am now happy.

Sound versions were announced back when the VT, RES and Colas trio were first announced. I will not be surprised to find next week’s announcement also contains rail blue, Intercity and TTG versions.

I thought sound versions were announced and the rolled back on instead sticking with the 6 pin decoder socket? It would be a logical one for the full sound upgrade and would save me doing the same work as JBM37404 mentions on my current one. That said for me it would have to be original two-tone green.

J39 was I understand very close but got delayed as they weren't happy with the running of test samples.

Class 14 is due this month or next according to the Bachmann website so must be on a boat somewhere.

Again according to the Bachmann website the RES Class 47 47795 "Royal London Society for The Blind" is due November/December. Ditto Totnes Castle and the Colas one.

Having tried a 128 model with Zimo MS580, MS590 and the new MS581, all perform similarly with the factory speaker.  It appears to be quite a low powered component for the speaker, but perhaps more importantly there is very little gap between it and the chassis, so not much of an enclosure.

 

Volume is therefore very low, and due to a less-than-perfect seal, a bit of crackle occurs.

 

Like many RTR speaker-fitted models, this is good for getting you going with DCC Sound, but there is usually something better possible.  In this case I would just insulate the SPK pads under the model's PCB and solder wires from the pads up to the main body cavity.  A YouChoos SugarCube8 speaker fits easily up there and sounds are massively improved.  Not much effort for a big improvement.

 

The model runs nicely.

 

As an aside, we also tried the model with a Zimo MN180 standard decoder, which works well, except that the decoder has a habit of heating up a lot and tripping its' thermal cut-out logic.  The solution to this is to disable any unnecessary protocols, such as Mfx, Motorola etc. by setting CV#12=4 (DCC protocol only).  If your system does not use RailCom, it is also worth disabling RailCom (switching off Bit3 of CV#29, value 8).  This reduces the amount of work that the MN processor needs to do and keeps the operating temperature down.

 

Hope that's useful.

John

YouChoos

 

Hi John

Thank you, that is very useful information which validates my suspicions about the speaker used. I really like the model in every other respect so I'll be on to you for a Sugarcube 8 in due course and just have to be careful when I install it. I hope Revolution Trains are gracious enough to take this feedback on board and if nothing can be done about the 128s at least factor it into the specification, design and fit for the sound components for the 120 which I, and many others I know are keenly awaiting.

Regards

Roy

Off topic slightly, but am I right in thinking that the Bachmann/Farish/EFE Winter announcements will be due next week? The last 3 months sure has flown by and my wallet is only just recovering from the Autumn releases 🤔. Not that it would stop me from finding the money if something I really like gets announced mind and I live in perpetual hope of a brand new V2 one day.....

Hi Roy.

 

We find your comments really interesting and this has confirmed what we have seen on odd occasions before in N Gauge models and smaller locos.

.

We have been working with Revolution Trains to provide sound files tailored to suit their models using ESU Micro Decoders, the circuit boards are designed as far as we know to ESU's specifications.   We never set up our Legomanbiffo sound files to suit the 'pre production' models, only those on actual sale as specifications & motors can change on the actual production models.

 

Our completed sound files for the Class 128 obviously had to wait while a production one arrived, thus many customers have recieved their pre ordered models at the exactly same time as we got ours.

 

The testing we have done over the last few days confirmed that the Class 128 model worked as designed, at all reasonable volume levels. But as the ESU decoders come as standard with the ESU sugarcube speaker & sound chamber kit, this obviously allows customers to have a choice of the fitted speaker, two speakers or just the ESU speaker, there of course is a 'No Speaker' option available.

 

Our Legomanbiffo comprehensive sound project, designed only for the Class 128 Revolution model, is being shipped out to all of our waiting customers from tommorrow (Monday).

 

For your intertest our project includes the following unique features to enhance you drivine experience.

Hi Charlie

I appreciate you taking the time to share all of the above, it is all very interesting and informative and of course I am very aware of your extensive knowledge and experience with absolutely everything DCC sound related. 

What has still not been explained (and this isn't I appreciate something you will necessarily be able to answer) is why the Zimo MS580N18 decoder I purchased with the YouChoos sound project loaded worked perfectly at default settings as supplied not just in the Farish locos tried which typically have Zimo decoders fitted in sound versions anyway, but also the Rapido Class 28 which is set up for an ESU decoder (in my case the two I have came so fitted) only the Revolution 128 has the sound-distortion problem and this is why I remain convinced it is the rating of the speaker that is the issue.

The level of work you have put into the sound project specifically for the Revolution Trains 128 is clear from what you have listed above and to be honest I wasn't aware of it. We all have our preferences and mine has always been to use Zimo wherever possible because of their reputation for high quality and resilience which has served me well for many years. That is not to say I don't have any sound locos with ESU decoders or have anything against them, and had I known about your sound file for this loco I might well have gone for it, so bringing the option to my attention is very much appreciated. However, of course the issue for me is that I have already spent the best part of the price I paid for the loco on the Zimo one and it is hard to justify another £130 ish (at a guess) for another decoder to fix the issue!

I accept that nobody was aware that the issue would arise with the Zimo decoder, but I am now in a position where I wouldn't want to even change the speaker for a better rated one that will suit it because of the risk of invalidating the warranty, so I am a bit stuck really, and with all due respect to Mike Hale I do not consider knocking down CV 266 to minimise the "crackle" a satisfactory solution.

For others though who haven't made a decoder or sound-file choice I am reckoning (knowing the quality of the Legomanbiffo sound files) you may have more than a few enquiries!

Best wishes

Roy

As mentioned above, I have taken the time this morning to do some swapping about of decoders between locos.

Having already tried the Zimo MS580 in the Class 31, I know that worked fine so next I have taken one of my Rapido 28s and swapped the ESU decoder from that to the 128 and vice versa. 

I reset the MS580 to default and set the 128 off, as expected the "crackle" returned big time.

I put the MS580 in the Class 28 and it runs perfectly with the Zimo, without any sound distortion whatsoever.

However the really interesting finding is that the 128 with the Class 28's ESU sound decoder installed (exactly how it came out of the 28) also runs without any speaker crackle whatsoever.

Then, even more interesting, I took the Zimo sound decoder from my Farish C Class and put that in the 128, and off it chuffed (seeming very strange) also with no crackle. I have checked the paperwork and that decoder, while a Next 18 is an MX658 so an earlier series of decoder.

For completeness the last checks I did were the MS580 in the C Class and giving it full acceleration off it chugged without any crackle or distortion whatsoever, although the sound of it changing gear was interesting, I then put the MX658 in the Class 28, again off it chuffed with no distortion.

So, in summary of the three chips tried in each of the three locos, all worked perfectly in the Farish C Class and the Rapido 28. The ESU and the MX658 both worked fine in the 128 without any discernible "crackling" but in that loco the Zimo MS580 (at default settings as tested in all locos) crackled like crazy. It seemed that the sound settings in the first two may have been a tad quieter.

What does this point to? I value others thoughts too, but what it strongly suggests to me is that the MS580's output is indeed higher, and while the speakers in the C Class and 28 are up to the job, the 128's is not.

Having experienced the problem myself I do have skin in the game here and it would be good to know what the speaker was rated at as the comments are it's a 'fairly standard sugar cube IIRC but it is fair to say that there are better speakers out there' does leave the door open to it being at the lesser end of a standard range.  My current choice for N gauge locos are 0.5 watt mini cube speakers and I've not noticed any distortion with MS series sound decoders out of the box as it were.

 

However, on the flip side this past couple of weeks I have been using sound projects from Digitrains that are not tuned to N gauge with some interesting aspects about functions due to their set up likely being for OO Dapol or Heljan products.  Before this week the only class 128s in town have been Heljan OO or O models with the sound projects most likely designed for the OO product when it was released.  So perhaps what we are experiencing are CV & volume settings aimed at bigger models with bigger speaker capacities leading to the resultant crackle when they instead find a 'fairly standard sugarcube'.  In that scenario we cannot blame RevolutioN for our purchases of a sound project being set up for a model expecting a much larger speaker.

 

But for the class 120 I would hope RevolutioN look again at how they specify the electric components, there is no price yet for the model as it's still being worked on so the opportunity to put in a decent standard rather than fairly standard speaker is still there without impacting on return on investment for the company.  If you are going to bury the speaker as it has been in this case, meaning replacement requires disassembly of the model then the quality of the item needs to be higher.

 

 

I too have successfully used the MS500 paired with a Microcube 5 speaker (0.5 watt 8 ohm rating) in a variety of projects and this has worked fine without any distortion even when (under YouChoos advice) increasing CV266 to 80 to improve volume.

Just like the MS580 the MS500 is rated at 1 watt audio at 8 ohm, so as far as I can see the output shouldn't be an issue for a typical Sugarcube speaker given that a decent lower rated microcube works without distortion.

I am asking Youchoos for their thoughts as to whether the sound file as loaded on the MS580 for me should ordinarily overpower a typical Sugarcube and cause such distortions.

Worth noting the Zimo manual still suggests CV266 =  64 as the highest "distortion free" volume.

As a long time customer (no other connection) I would trust YouChoos default settings as they have been doing sound on Zimo for donkeys years, and it is fair to say that personally I have fitted these to a good variety of locos both "plug and play" (6 pin and Next 18) and hardwired using a variety of different makes and sizes of speaker. However notwithstanding that, in this particular case I have taken CV266 right down to 40 which while much improved hasn't completely eliminated the problem.

As yet so far unexplained is why at default settings the decoder and sound file performed perfectly in the "plug and play" Farish Class 31 which also has a Sugarcube speaker, and failed to in the 128. Indeed my very first thought when initially encountering the "crackle" issue was to check the chip in another loco so as to rule that out as the culprit. I may well experiment further today, reset the chip to default settings and try it in a range of other N18 "plug and play" locos I have, Rapido 28 for one, to see if any present similar issues and while I am doing that I will try the 28's ESU chip in the 128.

I’m not sure why turning down the master volume isn’t seen as a genuine fix?

 

The speaker works fine (including the returned one) with different sound decoder/sound projects so I’m not sure whether it is the sound project or decoder amp that is causing the distortion. The speaker is a fairly standard sugar cube IIRC but it is fair to say that there are better speakers out there but that cost more (we have to find a balance between customers who want an easy sound upgrade vs customers who will never use sound).
 

We will continue to investigate. 
 

cheers Mike

Hi Mike

Well, I am somewhat taken aback - speaking as a purchaser of the 128 and potential 120 customer too I find that a really disappointing response. 

The simple answer answer to your question is because it is a bit of a "band aid" fix that doesn't address the underlying issue which is the speaker, as I have already mentioned this Zimo chip with that 128 sound-file loaded worked perfectly well in a Farish 31, so it does seem a bit lame to blame them.   Also, just to mention that although much improved, even with the CV value reduced to 40, my second 128 still has a slight crackle under certain conditions so isn't completely fixed. 

If you are saying that fitting a lower quality speaker than you might have is acceptable because not everybody runs sound then I am truly speechless - based on that logic why go to the trouble of fitting a 24 pin decoder socket to the 59 when not everybody uses DCC - surely a cheaper 6-pin one would do just fine?? It would also I think be fair to point out that from comments here and elsewhere it does seems to be the case that this speaker issue isn't isolated to a single type of chip or sound-project as is implied above, so further investigation most certainly does seem more than warranted.

As I have already said, the model is in every other respect lovely and a credit to all involved in it's development, just a shame that this one thing has become an issue.

The revolution team should be congratulated on the production  of a decent Class 128 DPU. The long awaited model could be a taster  for what can be achieved with many of the longer chassis designed DMUs, can’t wait for the Class 120 DMUs to appear having travelled miles on these in my younger days These classes of DMUs, certainly didn’t bounce around compared with the shorter chassis DMUs class 101 , 108 and 105s . Those 120s where the buffet bar had been removed , certainly made a comfortable area to list down after one to many lemonade shandys waiting for the last train home.
With the receipt of two class 128s and fitting  a Zimo sound chip, with the sound file of the Leyland Albion. The revolution design team have certainly given vast thought. At the time when the model was announced, I don’t know if the option of sound fitted or non sound fitted was given , however seeing that the models come with pre-fitted speaker, this is a welcome design consideration.

I can vouch for the best of the sound files representing the reproduction of the Leyland Albion sound for the prime mover. Lowering the sound level reduces the distortion and checking the seal on the sugar cube speaker pays dividends. Select the function to hear the second engine, the sound is awesome. Tweaking a few CVS the reported distortion disappears and the level is acceptable for home use. I find sound fitted locomotives in N Gauge at exhibitions the sound is lost. However, when at home it’s acceptable and after a period of time is not over powering. I would be interested to know through this forum which are the other distributors of Class 128 DPU sound file I have two different ones downloaded onto a Zimo next 18, one is streets ahead of the other and is he I remember the Class128 DPU , being thrashed. I will add I generally avoid buying models with the sound file already loaded on the chip preferring to consider the aftermarket offerings. 
The release of this model by revolution trains; and when I compared the models released in the last 12 months by the alternative manufacturers represents a significant challenge to the main stream N Gauge manufactures who really need to tighten their quality control processes.

The sound-file I have on mine was pre-loaded by YouChoos, it is of their Class 108 modified with sliding doors rather than slam ones (apparently I haven't tried that function). The 108 has essentially the same engines but with lower power rating than the 128 which of course could and did often haul a tail-load hence needing the extra oomph. I am quite happy with it, but whether another may be "better" I couldn't say as I have never heard a real 128 and is probably subjective anyway.

On the issue of QC I think a bit more balance is needed here as the 128 out of the box, lovely and really well designed though it certainly appears to be, is certainly not in many reported cases free from issues for the sound-user. The speaker crackle while possible to all but "fix" by reducing the CV266 master volume should not be there and it shouldn't be necessary to do that, I have tested the same Zimo sound chip in another sound enabled Next 18 loco (Farish Class 31) at the default sound setting and it was perfect - no crackle at all so there definitely is a speaker issue to investigate.

Opinions about what are "good" or "bad" will obviously anyway vary with experience, and no manufacture would claim to be able to deliver 100% of perfect models in any given batch - that just isn't realistic with mass production. My experience over the last 12 months has been mixed: -

- I have had to return two Rapido Class 28s out of three (one to Rails and one to Rapido) with a failed ESU sound-decoder (a common fault).

- One out of two Sonic J50s went back to Rails for replacement due to poor running.

- Two EFE J94s recently received are fine on analogue but I await micro-decoders to test them on DCC.

- I have purchased a non-sound Kernow Golden Ochre Farish 31 (the one I used for the test mentioned above), two sound-fitted Farish 4F 0-6-0s and a Farish sound-fitted Ivatt 2MT - all perfect.

- I received my first 128 with a speaker-crackle which Ben and Simon very kindly swapped for another at GETS last weekend, but sadly the replacement had the same issue.

What is more important to me is the response from the manufacturers to a given issue that is identified. Here, and to get back on topic, talking specifically of the case of my 128, the issue was speedily acknowledged by the Revolution Team and a commitment made by to investigate. For that to be done thoroughly will take time, so I am happy to wait, they are enthusiasts themselves and were clearly disappointed when I spoke to them - they want to and I am sure will get to the bottom of it. In the meantime run my 128 at reduced volume almost free from crackle until a "proper" fix is advised.

Hy guys just received my midland blue this morning and was wondering how the body is unclipped? Is it similar to the Dapol set up where you work you're way round the body shell easing it away?

Yes, just very gently get your fingernails underneath in the gap between body and chassis and it should ease out slightly then up. Be aware of the way round in relation to the chassis, apparently it only goes on one way round.

Got a response from RevolutioN today - turn down the sound, which has removed the crackle and once the body goes on it gets louder in all that empty space.

 

Gonna see how it goes, but it seems to have done the trick.

It is a "solution" I read about and tried yesterday, I shared by e-mail with Simon at RevolutioN although he may of course have already reached the conclusion through other means too. One point I would wish to stress though, is that while this is a "fix" of sorts and may satisfy some people which is great, it is only achieved by reducing CV266 down from default of 75 (to in my case 40) which pretty much eliminates the "crackle" but at the expense of making the sound quieter. I tested the chip in a Next 18 Farish Class 31 when at original settings and there was no distortion from the speaker, so unfortunately my conclusion remains that at least some of the 128 speakers as fitted aren't fully up to the job. 

In saying the above, of course it is early days and RevolutioN who are a very small team need time to fully investigate and possibly go back to the factory, I am sure we will hear from them in a more "official" capacity when they have done so.

On the positive side, speaker issue apart, I think the 128 is a gorgeous model, beautifully detailed and finished with a really well designed and smooth running mechanism, all of which which bodes well for the 120.
