rushdenx1 Posted November 2, 2009 Share Posted November 2, 2009 I want to invest in a Class 37 with sound. However my layout is just a Freight yard, consisting of straight track and only 6 feet long. Even so, I still want to be able to hear the 'thrash' of the loco either from a stationary position or witihn the 6 feet of track available. Can someone advise me on the best option. I have read that the Bachmann sound fitted 37's won't give the 'thrash' noise in such a small layout, can someone confirm this. If this is the case then is the best option having a sound chip fitted, if so which one, Howes, SW Digital, Loksound ?? And finally if I need to get sound fitted, who can provide a fitting service ? Sorry for asking so many questions, but I want to make the right decision and get the most out of the sound on the small layout I have. Any help is appreciated. Kevin.

The bachman one has notching will give you all the thrash you want when you want. Best to fit 2 x 23 ml speakers in the tanks though for the best sound as apposed to the original fitted speaker. Just found a utube clip i did some time ago showing what you want to achieve Link to post Share on other sites More sharing options...
The Black Hat Posted November 2, 2009 Share Posted November 2, 2009 Ive found that the notching on the Bachmann one still takes some time for it to kick in when running. My layout isnt particuarly long when you add the scenic sections to fiddle yards and moving about sometimes means they would run a similar distance. I would suggest getting a Howes class 37 sound chip, as they have both unrefurbished and refurbished power units, better to match your class 37 and also run better, going to power the engine of the locomotive, pending on how you drive it. I find that to be a far better set up - but then thats just perference. Link to post Share on other sites More sharing options...
Piemanlarger Posted November 2, 2009 Share Posted November 2, 2009 I dont rate the howes 37 on depot / short layouts, there is not much it does apart from rev like a boy racer! Much beter suited to tailchaser layouts. Link to post Share on other sites More sharing options...
rushdenx1 Posted November 2, 2009 Author Share Posted November 2, 2009 Thanks for all the comments so far and the great links. A question for Piemanlarger. Was it easy to tweak the Bachmann sounds. What did you do ? Link to post Share on other sites More sharing options...
Piemanlarger Posted November 3, 2009 Share Posted November 3, 2009 Thanks for all the comments so far and the great links. A question for Piemanlarger. Was it easy to tweak the Bachmann sounds. What did you do ? Yes, there was apost about tweaking Bachmann cv on old rmweb to get the 37 thrashing on a short layourt without using the notching. I prefere notching. , see if i can find it............... Fitting twin speakers is not too hard a job, just need to take the 37 apart and drill some 2mm holes in the tanks. I did have a post on old rmweb about doing it. not sure what the title was though. See belowe for cv tweaks SWD cl37 V4 CV settings for small layout by Sandhills TMD on Sun Jul 05, 2009 8:43 pm Hi Folks, Help required please ! Got the South West Digital class 37 version 4 sound chip installed in the Rail Express DRS pairing and even though the sound is good its not behaving on my very small 5 ft run. The gap between initial rev to get started and the full on power handle wide open sound is way to long for my board. Anybody got any values i can tweak the CV's too and make this better in short bursts ? Thanks in advance......................

This limits the max speed so it makes the chip thrash sooner. There may be another way of doing it but thats how i have seen it done. hope that helps cheers Simon Report this postReply with quoteRe: SWD cl37 V4 CV settings for small layout by SRman on Mon Jul 06, 2009 6:15 am What Simon says sounds as if it should work, in theory. However, I would suggest that if you do alter CV5, make sure you also alter CV6 (the mid-voltage setting) so that it is a lower value than that of CV5 (approximately half but you can experiment to see what gives you the best control). Re: SWD cl37 V4 CV settings for small layout by Sandhills TMD on Mon Jul 06, 2009 12:10 pm Thanks chaps, you are truely masters of the dark art of DCC 'tweaking' !!!! CV 5 at 10 CV 6 at 5 Result, mental tractor that goes from standing start to full power and whistle down again in less than 5ft ! Thanks again............... Im having a simlar problem with my Bachmann 37 do you reccomed the same CV settings? Also does anyone know how i would change them on a Hornby Elite as i havent got a clue and dont want to mess the chip up. Thanks Mark Hi Mark, Seems to do the trick. CV5 with a value of 20 and CV6 with a value of 10. You can also help the situation by lowering the value of CV3 ACC so the loco isnt too fast building speed. Sorted, CV5 changed to 25 CV6 changed to 12 Full thrash lovely, thanks all See if that helps, shopuld you get the Bachmann 37 Link to post Share on other sites More sharing options...
Poindexter Posted November 3, 2009 Share Posted November 3, 2009 I would stick with the Bachmann sound. Don't get me wrong I like Howes (My 20 is fantastic the 20 sound is the best I've heard) but when I got my 37's reblown I wasn't blown away by the sound when compared to a standard Bachmann. And as has been mentioned the Howes doesnt notch. For reference I got a refurbished and an unrefurbished version. Guy Link to post Share on other sites More sharing options...

SRman Posted November 27, 2009 Share Posted November 27, 2009 The only thing I don't like about the SWD / standard Bachmann sound settings is the enforced drop back to idle after moving off. In all other respects they are very good (apart from the class 20 on full thrash). I just don't see why SWD do that on their decoders, since many of the real locomotives can open up their throttles right from the word go. Link to post Share on other sites More sharing options...
Piemanlarger Posted November 27, 2009 Share Posted November 27, 2009 this is something i have asked about, it just does not look right with a loaded train. Hence my like for notching, so you can power away as with the 60 and 37 vid i posted this morning. Link to post Share on other sites More sharing options...
Bruce Depot Posted November 27, 2009 Share Posted November 27, 2009 Personally I don't like notching, I ordered my Howes chips for a small layout so they where configured differently. I can understand a normal chip needing more that 6ft to thrash and stop mind. Keith Link to post Share on other sites More sharing options...
tractor_37260 Posted December 12, 2009 Share Posted December 12, 2009 My latest bit of video (wonky) work Swd mk 4 class 37 on oil train (not being driven very well haha) Def one of the best ones I've heard/watched of late - you'll be getting nominated for a utube "Oscar" soon at this rate. However, it does sound more like a Bachmann chip using notching to me, than an SWD one ? perhaps not ? as there's no flange squeal on the Bach chip The 60 oil train is also very good, but alas 60's don't do it for me, like 37's Link to post Share on other sites More sharing options...

I just don't see why SWD do that on their decoders, since many of the real locomotives can open up their throttles right from the word go. It does sound a bit odd, and it happens on a lot of sound decoders. On a real loco once the throttle (air valve) is opened - it stays opened unless it's manually closed. The engine revs do not drop back to idle unless the throttle is closed again. Recently noticed on the Hornby sound 60, this drop back to idle once moving does not happen ! even if only moving off and staying on speed step 1 (128 steps) the engine remains above idle sound, only dropping back to idle once stopped. Let's have more sound decoders set like this Link to post Share on other sites More sharing options...

Clagmeister Posted December 14, 2009 Share Posted December 14, 2009 Why would you want thrash on a short layout. You would be modelling a loco being driven by an idiot! If I thrashed up and down 12A I'd be out of a job within weeks. Sound has to be realistic too! cheerio Claggy Link to post Share on other sites More sharing options...

If I thrashed up and down 12A I'd be out of a job within weeks. Sound has to be realistic too! cheerio Claggy hmmmm i can think of a few drivers who would also be out of a job too!! in all fairness its just a model and if people who dont have big layouts (like me) want their locos to "thrash" over a short space then its up to them, realistic or not, after all why spend ??100+ on a model only to have it never get out of "notch 1" so to speak, a lot of my locos have been set up by howes to give a bit of "thrash" low down but not go carrering off the end of the layout at breakneck speeds!! a good feature on my class 40 (howes) is when its crawling along on shed in about notch 6-7 it gives a momentary burst of sound every so often as if the driver has opened the throttle to keep it moving, the loco however doesn't speed up at all, the unrefurbished 37 also has the feature of wheelslip where if you open the throttle straight up it will "thrash" then breifly spool back then trash again as if its slipping where as if you accellerate slowly through the notches then it wont slip and it will throttle up without spooling back i've added a youtube video of the 37 on bobs big layout http://www.youtube.com/user/fastlinegrid#p/u/5/YxLXTej-Nwc and heres one of it on my 6ft layout http://www.youtube.com/user/fastlinegrid#p/u/23/bwWROw1AXyI Link to post Share on other sites More sharing options...
