I am a "Nay Sayer" and with experience. My first couple of layouts in the late 60's-70's had brass track in a clean A/C environment and required constant cleaning (as in every time they were used). They developed the use of NS to help eliminate some of the effects of oxidation and to have better conductivity through the track system. Also, the oxidation of NS is somewhat conductive, still allowing operation to a point. Those of you that haven't had problems with brass are very lucky and an exception.It would be interesting to know just how many of the "Nay Sayers" have actually had experience with the dreaded brass track??

With NS track, I generally do a scheduled preventative maintenance cleaning of the track once a month (or so). Running trains often does help keep the NS track healthy, but the key is to have both track and wheels kept clean and the use of metal wheels.
My opinion on brass: If the hobby still had nothing but brass track...I would not have returned to it in my retirement. That's how strongly I feel against it.
