34 TRACK. 



Proper expansion must be secured by the use of iron shims, 

 provided in accordance with the above specifications, except 

 where track is laid on a steep grade, when sawed wooden 

 shims of proper thickness will be provided. These shims must 

 be left in place until track is full spiked, bolted and thoroughly 

 anchored. 



In order to prevent rails from "creeping," it is absolutely 

 essential that each individual rail shall be so thoroughly 

 anchored as to insure freedom from contact with adjoining 

 rails. Creeping cannot be prevented if a number of consecu- 

 tive rails are in contact 



BOLTING. 



The Harvey grip, or other improved form of bolt, should 

 be used. At the time the rail is laid, two bolts should be 

 placed in each splice, and tightened sufficiently to hold rails in 

 line. The remaining bolts should then be placed and tight- 

 ened as soon as possible. Nuts should be tightened a second 

 or third time within 30 days after track is laid. 



Inspect the rails before angle bars are tightened, and take 

 out kinks or bends by the rail bender. The nuts must be 

 screwed up firmly before joints are spiked. 



GAGING. 



The standard gage will be as follows: 



On tangents 4 ft. S'fe ins. 



On curves of 1, 2 and 3 degrees 4 " 8% " 



On " " 4. ft " .4 " 8% " 



On " " 7, 8 " 9 " 4 " 8% " 



On " " 10. 11 " 12 " 4" 



On " 13, 14 " 15 " 4 " 9*6 " 



The extra width of gage on curves should be uniformly de- 

 creased or tapped off, on the easement curve, from point of 

 full curve to point of tangent. 



Joints and centers should be gaged first, and the track gage 

 must be applied at as many points as may be necessary to in- 

 sure perfect and uniform gage. 



Easement curves must be spiked to gage at five different 

 points within each rail length, and all track must be accur- 

 ately gaged when spiked. 



Suitable track gages for use on tangents and curves, which
