LOADING AND UNLOADING CARS 339 



matically assumes a position parallel with the track, ready for 

 the following car. 



A satisfactory device used by a redwood operator in California 

 for unloading logs from cars consists of a 20- by 28-inch timber, 

 placed across the track at an angle of 45 degrees, and securely 

 fixed at each end on solid supports. The base of the beam is 

 about 8 inches above the upper face of the car bunk. The 

 loaded train, one log on each car, is brought in from the woods 

 and pushed along the track toward the unloader. The logs 

 striking the slanting timber are pushed off the car as the train 

 advances. When half of the train has been unloaded the loco- 

 motive is uncoupled from the rear of the train, run around and 

 attached to the forward cars, and unloading is continued until 

 completed. Thirty thousand feet of logs can be unloaded by 

 this device in three minutes.
