d. Loading factors.

(1) Tight loading. Pallets should be placed

tightly in both ends of the car. Generally, for practical

purposes, it is necessary to have some side clearance

space of approximately 1 to 2 inches between pallets in

order to maneuver the pallets into place by the forklift

truck. As shown in section AA, figure 3-23, the total

crosswise slack space between pallets and sidewalls in

the car is relatively small (approx 6 in) and, ordinarily,

would not require any additional crosswise bracing.

(2) Side shifting. In order to prevent side

shifting of load and with a possible derailment of car in

transit, circular 42F, Operating-Transportation Division

this method, the bracing can be removed at destination

and with this work space in the doorway section, the car

can be unloaded without difficulty.
