LOCATION. 9 



The ability of the engineer will be determined by this 

 standard. 



Before any new road is located, the Chief Engineer will in- 

 dicate the character and purpose of the line, and will give the 

 number of trains for which the line is to be located. After 

 the completion of the preliminary surveys he will also deter- 

 mine the rates and proper adjustments of the ruling grades 

 and the maximum degree of curvature to be adopted. All 

 locations must be approved by the Chief Engineer before con- 

 struction is begun. 



Each railway location should be specially considered with 

 reference to its effect upon receipts, operating expenses, and 

 fixed charges, the character and direction of the expected 

 traffic and the class and number of trains to be operated over 

 It. The selection of route, adjustment of location details and 

 character of construction will be determined in accordance 

 with the ascertained conditions of lowest operating expense 

 and least construction cost for each case. 



Locating engineers will furnish weekly reports, stating 

 progress and giving all other items of general interest pertain- 

 ing to their work, especially information concerning present 

 or prospective sources of traffic, its locality, character and 

 amount. 



Strict compliance with the instructions is expected con- 

 cerning the preparation of maps, profiles, records, and esti- 

 mates. 



Graphic tables for computing quantities on transverse slopes 

 for use in preliminary estimates will be furnished by the 

 railway company. 



So far as practicable, all maps, profiles, estimates .and gen- 

 eral records will be completed while the surveys are in prog- 

 ress, avoiding all unnecessary accumulations at the close of 

 the work. 



Competent engineers will avoid much unnecessary loss of 

 time and money by making preliminary reconnoissances im 

 person, using pocket compass, hand level and "aneroid" when 

 necessary. When there are several alternate routes careful 

 examination will usually prove it unnecessary to make instru- 

 mental surveys over them all.
