chl84 Posted June 18, 2011 Share Posted June 18, 2011 Hello all!I have just bought a Digital GWR Western Pullman set.Its all very lovely, but I was a bit taken aback by the buzzing noise the select unit makes. Its not very loud, but noticeable. Also, when I but one of the digital trains on the track, that makes a buzzing/hissing noise as well. Again its not very loud, but noticeable until the train starts moving. I'm just using the track that came with the set.I just wanted to know if this is the normal noise it makes, or if there is something funny with my set.

Ali oop Posted June 20, 2011 Share Posted June 20, 2011 My elite emits a slight buzzing noise as well, its noticable in a quite environment, i.e. no back ground noise. I suspect its the power supply switching as part of any internal DC conversion going on. My units been happily functioning for approx 3 years without issue or change to the background noise. So if yours is nothing more than a quite buzz I wouldn;t be to concerned, you could check with your supplier if concerned and test another unit.The only thing I would check would be your connections from the output terminals to confirm that they connect bare metal to bare metal otherwise if any insulation is between the contact surfaces then it might could some heating/arching.Hope this helps.

chl84 Posted June 24, 2011 Author Share Posted June 24, 2011 Thank you for your response, i tested another unit and it is the same, so no need for concern! Nice to know its normal! Link to comment Share on other sites More sharing options...
GraemeWatson Posted June 26, 2011 Share Posted June 26, 2011 Hello there, I have the GWR western pullman set too, I believe this is due to an old Hornby decoder being fitted to this set. Newer hornby decoders, and newer digital sets do not seem to have this problem. The buzzing sound is particularly noticeable on the Castle class.

I'll think about putting a new chip in it if possible, but in no rush! Thanks for the replies. Link to comment Share on other sites More sharing options...
