MOTIVE POWER AND ROLLING STOCK 32 1 



Five engines were in constant use in hauling on the main line 

 and spurs; one locomotive was used by the loading crew and 

 construction train; and one was held in reserve. 



An Alabama longleaf-pine operation with 24 miles of main 

 line, and from 5 to 6 miles of spur used fifty-three forty-foot flat 

 cars to haul daily from twenty-five to thirty cars of logs (70,000 

 to 90,000 feet, log scale). These cars had a rated capacity of 

 60,000 pounds and each carried from 2500 to 3500 feet, log scale. 



The logs which were hauled 6 miles over a trunk-fine rail- 

 road, were loaded on cars provided and kept in repair by the 

 trunk-line railroad which also furnished one 65-ton rod engine 

 for use on its track. 



The logging company provided one 54-ton rod, one 40-ton 

 rod, and three Shay locomotives of the following weights, 28, 

 32, and 55 tons. The rod engines were used on the 18 miles of 

 main-line logging road, while the 32- and 55-ton Shays were used 

 on the spurs, and the 28-ton Shay on the construction train. 



On a western operation where 200,000 feet were hauled daily 

 over a 3-mile main line with a 5 per cent grade and many curves, 

 a 55-ton Heisler was used on the main line and a 35-ton Heisler 

 on the 3I miles of spurs. Forty 40-foot flat cars were required 

 to handle the output.
