will insure the retention of the proper gage during the oper- 

 ation of spiking, must be used. All track gages must be tested 

 by the engineer or roadmaster at the beginning of the working 

 season, and the date of inspection recorded. 



SPIKING. 



Track must be full spiked, with inside and outside spikes 

 driven in opposite sides of the tie. Spikes must be set half 

 their own width from edge of rail and driven vertically to a 

 full bearing on foot of rail. The prevalent practices of driv- 

 ing sloping spikes, or of giving them a final lateral blow to 

 close the spikes against the rail, will not be permitted. So 

 far as possible the spikes will be driven in the best wood in 

 the tie, which is usually at the outer edge, and must not be 

 redriven in old holes. 



ELEVATION. 



The elevation (in inches) of outer rail upon curves will be 

 made in accordance with the following table: 



TABLE OF ELEVATION OF OUTER RAILS ON CURVES. 

 Rate of speed in miles per hour, 



The greatest elevation must not exceed 6 ins., unless other- 

 wise directed. 



The elevation of outer rail on curves must necessarily be 

 adapted to speed and other local conditions, with due regard to 

 safety, comfort and economy of track maintenance, for all 

 classes of trains. 



The elevation on mountain grades should not exceed that 

 required for 25 miles per hour.
