Hello kakingmm and welcome to the trainz forum...
As ct krogen has said, this sounds like a bad install, my advice is uninstall Trainz, and then reinstall Trainz and see if that works, also let us know when Trainz was installing, did it mention any errors or problems with the install, and did you receive all green ticks in the Trainz Diag box.?.
You can check the Trainz Diag box at anytime by going to the Auran Folder in Drive C: program files, click on the Trainz Diag and see if you get a line of green ticks, if you don't, there may be a hardware problem with your system, let us know where any red X's show up, and we may be able to help you further.
Usually after Trainz 2010 has installed onto your system, it should go through a full extended database repair, if this has been stopped at any time, then this can cause a problem with missing items in trainz.
Hope the above helps
