Stephen-1260829 Posted June 12 Share Posted June 12 (edited) Finally!! My class 50 arrived, along with 5 MKII coaches ( 3x Tourist Standard Open, 1 x First Open, 1 x Brake Standard Open) arrived from Rails of Sheffield. The loco and coaches were very well packaged up. I have not run the loco on the track yet, I will do this on Friday afternoon. Fingers are crossed, hoping that there will not be any drive shaft issues!! the boxes are standby just in case the loco needs a trip back to Sheffield. i have added a short video of Leviathan and three coaches on my test piece track board. (ignore the AT-AT in the background 🙂 ) VIDEO-2024-06-12-18-33-40.mp4 Edited June 12 by Stephen-1260829 8 Link to comment Share on other sites More sharing options...
Task Posted June 18 Share Posted June 18 Hi, so I just got my BR Blue Class 50 (Decoder fitted) and when it sits on the track idling it makes quite a loud humming sound. The humming gets a little louder when I turn on F0. Is that something happening with all the Class 50 models or do I have a faulty one that I should get replaced?

Postman On The Rails Posted June 18 Share Posted June 18 @Task a video might help, the 50 makes some noises while stationary and ticking over. Link to comment Share on other sites More sharing options...
Rallymatt Posted June 18 Share Posted June 18 If you turn the sound off (1) does the humming go away? All locos will hum a bit when the sound is off, with a a DCC loco they are live all the time. As Postie says a video would help to see (hear) if it’s excessive 😁 Link to comment Share on other sites More sharing options...
Task Posted June 18 Share Posted June 18 @Postman On The Rails @Rallymatt Here it is: The humming is always there, the video is with sound off. With sound on you can't really hear it as the sound is louder. Thanks for you two trying to help 🙂 Link to comment Share on other sites More sharing options...
Rallymatt Posted June 18 Share Posted June 18 (edited) From that description and clip I would say that’s absolutely fine. If it’s running well then no problem. As I said all DCC locos will hum because they are taking power all the time, the shape of the body shell can make some hum louder than others. My Piko BR 130 with an HM DCC decoder in and the class 50 profile has quite a noticeable rumble with sound off but power on. Runs like a …. Well like a train 😁 Edited June 18 by Rallymatt 1 Link to comment Share on other sites More sharing options...

A simple procedure carried out on a clear track. Ensure F0 (lights) is off as this is the starting gun. Set CV149 to value 0 in the app. Press F0 and the loco will race off at max chat for about 1.5-2m then stop. Job done. CV149 will now show value 2 and the associated motor PID settings will have been adjusted. Your loco should run much better. Edit to amend CV148 to CV149 Just fitted a Bluetooth decoder to my Class 50. All fine after I got the hang of the app but I now have a noisy loco (no, not the sound file 😄) which slightly wobbles; the noise increases with speed. The CV149 is already set to 2 and I cannot seem to change it to 0 for the above fix. Any ideas. Thanks. Edited June 20 by Renoir Additional information : the noise is not a hum but rather a slight raspy sound Link to comment Share on other sites More sharing options...

With both of mine, if they were to tight, it made a noise. 4 Link to comment Share on other sites More sharing options...

HM DCC decoders are full DCC decoders and the app is like falling off a log with setting up, so so easy. Then flip to DCC and away you go. I really recommend getting 1 decoder and trying it. I love my Zimo decoders too but HM DCC ones are so user friendly. Took your advice Matt...very pleased with the outcome and opened up a new world to me. Many thanks for the encouragement. 1 Link to comment Share on other sites More sharing options...
