receives its steam, hooks on to an incoming load and spots it on the 

 incline proper. This spotting engine also kicks the empties over 

 the switch and upon the gravity spur track. The descending load 

 brings up the empty car — standard Northern Pacific flats — their 

 passing taking place at the middle of the incline. The load is under 

 brake control for the entire distance, it being necessary to use steam 

 only at starting. A trip from the headworks is made in six minutes. 

 A daily output of 50 cars, or 250,000 feet, could be readily handled 

 over the incline in a 10-hour working day, this being at the rate of 

 five cars per hour, or one car in twelve minutes. 



The total cost of the incline — construction, installation of equip- 

 ment, equipment, etc. — was approximately $22,250. This cost may 

 be itemized as follows: 



1. Cost of clearing right of way for incline proper and gravity 



sidings, top and bottom, also site for headworks and hoist $500 



2. Cost of grading right of way 2, 000 



3. Cost of laying and surfacing track, dirt ballast was used 800 



4. Cost of headworks, including labor, material, equipment, etc 150 



5. Cost of installing hoist, including labor and material, etc 1,000 



6. Cost of ties 900 



7. Cost of steel and fixtures (60-pound steel, at $40 per ton) 4, 200 



8. Cost of track rollers 400 



9. Cost of lowering line (5,800 feet of l^-inch line) 3,200 



10. Cost of lowering engine, f. o. b. Portland 6, 500 



11. Engineering 500 



12. Miscellaneous (labor, equipment, freight, etc.) 600 



13. Spotting engine (second hand) with equipment 1,500

The cost of operation, including depreciation, maintenance, sup- 

 plies, etc., is estimated as below. In this estimate it is assumed that
