Hi Everyone thank you all so much for spending your time trying to help, still not really sure what the problem is but maybe a replacement controller is worth a try now. I have recorded one of my trains running on my old controller and the new one both with their respective transformers: Old C912/R965 - notice the slow speed control New P9000w/R7229 Hopefully this will help explain what i'm experiencing better Also decided to do the same thing with my Bachmann : Old New

hi Chis thanks for replying ive tried using the p9000 as well could i have a variant of this that is also outputting AC? The trains i have are all around a decade old. (i think) i have a hornby R150 and a Smokey joe, got around the same time. and a bachman 170/4 32-452 They all make loud humming when started do you know if thease are old enough to case problems with PWM?

Recently got back into model trians and after a few hours my old R965 controllers died. I brought a new R7229 controller to replace them. Using this it creates a very loud humming noise from the trains when the power is on any level and at about 2/5ths power they start to move slowly. I have tried this controller with both p9000 and c912 transformers. im guessing the contoller is defective but not looking forward to spending more money right now and returning anyhting is going to be difficult. does anyone have and advice on what else could be wrong?
