Marty F,
I agree with you 100%, however I have to tell you I used the 1st Generation FasTrack with the Black Center Rail, and as long as I used your other disciplines for building my fair sized FasTrack 5 level DCS layout, it ran with all 10's, course these were the days of magic lights also. Now the full layout was not by any means all black mid rail, I would say about 1/2. I never removed any of the paint from the mid rail any where on the layout, and it was a pretty fair sized layout, with almost 40 switches. I never did have a complete large layout, with all Black mid rails however. The entire layout ran with all 10's thanks to both you're and Barry's great advise. If I was purchasing new track today however, it would have no Black mid rail, however I do purchase some of the 1st generation FasTrack used, every once in a while, it has not been a problem on my layout what so ever.
