Railway Gauges. 



163 



ways average the same number (13) per car, we have the fol- 



lowing table 



A difference of 26,000 lbs, or 13 tons, in favor of the narrow 

 gauge, or 2,000 lbs. per head per passenger. Assuming the 

 weight of the broad-gauge car to be only 15 tons, or 30,000 

 lbs., the difference in favor of the narrow-gauge cars will still 

 be 18,000 lbs. or 1,384 lbs, per head for each passenger, as 

 against 923 lbs. per head by the narrow gauge. So much for 

 passenger traffic ; now let us see how the account stands with, 

 regard to freight. The average weight of the most recently 

 constructed broad gauge cars is 20,000 lbs., capacity 20,000 lbs. 

 The average weight of the southern broad-gauge cars is 18,- 

 500 lbs., capacity 16,000 lbs. But to make it as favorable as 

 possible we will consider their weight to be 18,500 lbs., capac- 

 ity 20,000. 



The average pounds of dead weight to one ton of paying 

 freight carried on railways in Massachusetts and New York 

 in 1870 was: 

 Massachusetts 3,136 NewYork 3,109
