A towering guard tower, multiple layers of security barriers, covered train unloading areas and earth-covered bunkers indicate this is probably a sensitive site.

There are also two earth covered bunkers along the SW perimeter line a larger one to the north and a smaller one at the south corner of the secured area. Also, if you follow the road up the hill from the site there is another complex neat the top, which also shows signs of being a high security area. Due to the large amount of vegetation and extensive recreational facilities on the site I am inclined to think that it is a civilian, rather than military facility, which would also be consistent with the satellite launch center. Something I'm not seeing is any equipment for moving the contents of the cars into the bunkers or buildings, such as a large crane.
My best guess is that it may be a facility for handling solid fuel for launches at the space center. Other high security operations requiring specialized railcars could include mobile launchers for missiles, transportation of nuclear materials or warheads, or nuclear waste.
As a side note, if you look directly between this facility and the next green spot to the southwest you can see the remains of a large facility which has been bulldozed.
