RMweb Premium cnw6847 Posted May 27, 2014 RMweb Premium Share Posted May 27, 2014 I bought a Bachmann 45 tonner and tried it on DC where it performed nicely and pretty quiet. When I put it on DCC its quite noisey and takes a lot to get it going. I am only a beginner with DCC, just wondered if anyone has any ideas to why its noisey under DCC? I am using a new NCE powercab set. thanks in advance Link to post Share on other sites More sharing options...
DanielB Posted May 27, 2014 Share Posted May 27, 2014 You might get better luck in the dedicated DCC section - there's a wealth of information and some incredibly helpful chaps in there. Link to post Share on other sites More sharing options...
298 Posted May 27, 2014 Share Posted May 27, 2014 I can replicate the same at home, but can't remember my 45 tonner being particularly noisy. I'm assuming it's fitted with a factory chip- exactly what kind of "noise" is it...? Link to post Share on other sites More sharing options...
RMweb Premium cnw6847 Posted May 27, 2014 Author RMweb Premium Share Posted May 27, 2014 thanks for the replies, I thought i'd put it in the USA section incase anybody had come across same thing. Its hard to describe, sort of a buzzy sound especially at low speeds. As I mentioned it doesn't do it with DC Link to post Share on other sites More sharing options...
M Graff Posted May 27, 2014 Share Posted May 27, 2014 It is most likely the VERY crappy factory installed decoder! Replace it with a good one, and I can almost guarantee that it will be silent! Link to post Share on other sites More sharing options...
M Graff Posted May 27, 2014 Share Posted May 27, 2014 Here is a video where you can see the difference, sorry for the bad sound, but it is better than nothing... Link to post Share on other sites More sharing options...

I think i'll try another decoder! Link to post Share on other sites More sharing options...
298 Posted May 28, 2014 Share Posted May 28, 2014 Mine does the same, although it doesn't really bother me as it isn't used that much and I was aware of the limitations of its cheap decoder. Link to post Share on other sites More sharing options...
Railtunes Posted November 11, 2014 Share Posted November 11, 2014 Maybe it's because you've overloaded it by a ton. Isn't it really a 44 tonner? Link to post Share on other sites More sharing options...
RMweb Premium cnw6847 Posted November 11, 2014 Author RMweb Premium Share Posted November 11, 2014 Bachmann make 44 and 45 tonners. The 45 tonners have outside motion cranks on the trucks the 44 tonners don't. Link to post Share on other sites More sharing options...
long island jack Posted November 11, 2014 Share Posted November 11, 2014 it's the cheap decoder,i run one on HELM and it buzzes at low speed,doesn't bother me that much,you don't really hear it when it's at a exhibition with all the back ground sounds. people are always asking me how i get it to run that slow pushing 2 boxcars,it can be done with a bit of fine tuning,but you still have the buzzing.

enginelane Posted November 11, 2014 Share Posted November 11, 2014 Hi I converted mine to run as an industrial shunter in the scrapyard on a modern image UK layout. It needed to be well run in and compared to other locos who set off at say controller setting 2 or 3 needs be set at 12. It buzzes then when it sets off it can be brought down to 5 or 6 and it runs. As in last post the noise is not too noticeable especially when there is a Class 66 burbling away in the next siding. I have found that the small wheels pick up dirt quicker than other locos and does need cleaning more often Link to post Share on other sites More sharing options...
