the same basic design except for the
superstructure which is designed for specific
uses. Figure 1. 3 shows some of the more common
railway cars, and the use for which each was
designed is readily apparent. You could haul
coal in a boxcar, but you probably would not if
you had hopper and gondola cars. You would want
to save the boxcars to haul freight subject to
pilferage or weather damage. On the other hand,
you could use boxcars for troop movements if you could not get passenger
cars.
Figure 1.3. Common Railway Cars.
Although the cars shown in figures 1.4 and 1.5 are not presently in
the Army's worldwide inventory of rail equipment, they are included to show
the technological advances in the design and construction of commercial rail
equipment. As new equipment is developed for commercial railroads, military
transportation planners explore the possibilities of applying the new
concepts and designs to military rail equipment.
The multilevel rack car, shown in figure 1.4, reflects the emphasis on
larger loading capacity. Such equipment is being developed to keep pace
with our Nation's increasing demands for
