OK that sounds good.  I think ill go with the gray.

I am the newest of newbies.....I only have the Pacific Flyer set which has a small oval and 4 cars pulled by a DC locomotive.  I want to buy a Track Pack so I can have a larger layout.  It seems that the gray bed track would be better quality so I would like to get that version. I was told that you need to have the gray track in order to run the DCC locomotives but I'm not able to upgrade to DCC from DC yet.  Can I still run DC motors on the gray track?  I don't want to have to buy all new tracks when I upgrade to DCC.
