The Mercury Capsule Launching Car No. 3413 would launch a Mercury Capsule located at the top of the rocket into space and return it to earth with the aid of a parachute. The RED flat car frame No. 6511-2 was NOT numbered. Variations occur with the rocket decal that was either DARK BLUE (illustrated) or LIGHT BLUE. The platform also has two different shades of GRAY. Shown is the LIGHT GRAY variation, but there was also a DARK GRAY. None of these variations are rare. The car came AAR trucks, some of which have only one operating disc coupler. Produced in 1962 through 1964, the railings are often found broken on this car.
