This is the interactive load (in orange) for interactive NASA_SRB_Cars 1 and 2.
When loaded there would be a solid rocket booster for the space shuttle inside. These cars are relativly hush-hush
as evidenced by the lack of reporting marks following capy, ld limit, and lt wt. Pictures show these as apparently
being painted over. When being moved, idler cars (supposedly filled with water) are spaced between cars. Movements
are slow and security is high. When loaded these are effectivly bombs. They are also wider then a normal car as the
solid rocket boosters are 12 ft in diameter. No external indication is given weather the car is loaded or not but a
look at the amount of compression of the bogey springs might be an indication.
