Hi Dave --
If it's a "no show" it usually means that one or more of the dependencies is missing.
In most cases this is the bogey, but sometimes it can be couplers or in the case of locomotives the sounds, cab, ... .
TrainzObjectz tells me that this particular freight car needs:
Bogeys kuid 98966:50010
Couplers kuid 98966:50001 and 98966:50002
If you download these from the Download Station the freight car might work.

Are u using TRS2004? If so u should install and learn how to use TrainzObjectz - it is the most useful tool available for Trainz and one of several reasons why I prefer TRS2004 to 2006. If you don't have TrainzObjectz, a Google search will locate it.
If u are using TRS2006, sorry but u will just have to get by with CMP.
Best,
Phil
EDIT:
Hmmm. Interesting. The couplers are on the Download Station; the bogey isn't.
Dave - for the bogey, go to the link I provided to download the freight car. Towards the top you will see a link to Rolling Stock Parts. You will find the bogey on this new page.
