inspected, and it also reveals tampering.
However, the seal offers little
protection.
Rigid accountability of seals should be maintained.
This will
prevent the undetected replacement of the original seal with another.
Protection is provided by a heavy duty padlock, or it is provided by tightly
twisting a length of heavy wire through the locking eyes and closely clipping
the loose ends of the wire. Padlocks, however, advertise valuable cargo.

(3) Grouping cars.
It
is standard railroad practice in making up
trains to group cars according
to their destinations.
However, cars having
sensitive or pilferable freight
should be grouped together if possible. This
will aid the most efficient use
of security forces.
(4) Open cars. Open, flat, or gondola-type cars cannot be locked or
sealed. When this type of car is used, the security force must take certain
steps. They must place themselves so as to permit continuous observation and
protection of the open cars.
