FIGURE 22 illustrates the relationship between the side

will be seen that the improved railway car adequately con
forms to this AAR standard; it may be mentioned, how
ever, that the shed structures for longer cars should be
correspondingly narrower.
At the last minute, the weather shed area of car A can
be loaded with additional 1.c.l. ‘freight for shipment either
to Los Angeles or to intermediate points. This is a very
convenient way to get l.c.l. shipments to intermediate
points, because the seals on the containers themselves
do not have to be broken; and by keeping the two main
Los Angeles containers intact for the entire distance, there
is no danger of any of that load being dropped olf at
the wrong point, nor is there any danger of pilferage.
