With most operating accessories, I hook them up to a 1033 (or any variable voltage) transformer, on the track voltage posts, that are controlled by the handle. This way I can vary the voltage and see what voltage setting I get the best operating results from. Its a combination of speed and noise. Once I like the operating speed, I measure the voltage with a meter so I know what I want. After that, I connect it to one of my auxiliary transformers that deliver the desired voltage.
I have a Lionel saw mill, and the Atlas turntable, both of which operate on dedicated transformers, so I can control the speed properly. A little expensive, maybe, however some of these items only run properly when running at a specific narrow voltage range. I tape the transformer handle in place, and label it with the desired voltage setting in case it gets moved. Its important to label the voltage setting, as you will forget and have to experiment all over again to find the setting you like.
The good news about the noise, as you get older, you don't notice it as much. Not sure if I am loosing my hearing or just learning to tune it out.
