1.14. RULE 4MAXIMUM LOAD WEIGHT, SINGLE CARS
The weight of the load on a car must not exceed the load limit
stenciled on that car. The weight of material loaded between truck centers
and the ends of the car must not exceed 30 percent of stenciled load limit
15 percent each end. For example, if the stencil on the car reads LD LMT
104,000, you know you may load 15,600 pounds at each end of the flatcar,
that is, between the truck center and the end of the car.
If the load length is less than the distance between truck centers,
only established percentages of the stenciled load weight limit can be
loaded unless the car owner has designated otherwise in The Official Railway
Equipment Register. Established percentages differ for fishbelly and
nonfishbelly flatcars. When the load is lapped or staggered between truck
centers, covering about the full length of the car, and does not exceed the
stenciled nominal capacity of the car, the percentages shown in the
following subparagraphs do not apply.
a. Fishbelly. The fishbelly design gives a car greater carrying
capability than the nonfishbelly. A load extending 18 feet or less between
truck centers can equal 75 percent of the stenciled limit, as the sketch
shows. If the load is longer than 18 feet, it can weigh 100 percent of the
limit.
