Yes. When Lionel first came out with FasTrack it had a black center rail. Production of that was stopped when it became obvious than it made the center rail "stand out". When I first saw FasTrack at Nicolas Smith Trains around 2005, both were in stock, so I could compare them side by side. I bought the non-blackened version.
