The efficiency of this car is a simple mathematical problem. Compare this 4-Bunk Car with a Flat Car with four bunks of the same capacity and note the saving. The percentage of dead weight to log capacity is 30% as compared to 36¼% for the flat car or a car cost per thousand feet logs of $78.50 as compared to $93.50 for flat car. This means a saving of 20% on the haul back of empty cars and nearly 20% in first cost.
Where a large percentage of logs from 12 to 20 feet are handled, this Quadruple Bunk car has a great advantage over any other type. The construction is such that the entire load can be carried safely on the two center Bunks. Logs in length from 12 to 41 feet can be carried with equal facility.
Details are as follows:
Westinghouse Air Brake, Automatic Couplers, Tandem Spring Draft Rig, Two Main Sills 10 × 10 in., forty feet.
The Bunks are arranged to dump the load on either side.
Two Side Sills 10 × 10 in. extending from Bolster to Bolster. Each Side Sill is trussed with two 1½ in. rods. Two intermediate bunks are located directly over cross ties. Bunks are 10 feet long equipped with Knight chocks.
Bolsters are built up of Structural and Cast Steel of ample capacity to carry load.
Trucks are Standard Arch Bar type with 4½ × 8 in. Journals. 33 inch chilled tread double-plate, Griffin wheels. Structural Steel Bolsters and spring plank. All metal Brake Beams inside hung.
This car is equipped with all necessary steps and handles and meets the requirements of the Inter-State Commerce Commission and the U. S. safety appliance laws.
