RAILWAY STATISTICS. 



[The following Tables have been compiled from Mr. Whishaw's 

 work on the Railways of Great Uritain.] 



Table A gives the total lengths of railways, from which it appears 

 that of .')8 railways enumerated, 16U9i miles in length, 31 (measuring 

 319'J miles) are under twenty miles in length, suggesting a great waste 

 of capital in the management. 



Table B gives the lengths of 58 railways distributed as single and 

 double lines of railway, by which it appears that not more than a sixth 

 are single lines of railway. 



Table C shows the number of miles of single and double railways 

 laid down upon each gauge for 17o<j miles of railway, with the total 

 of miles of single railway laid down on each system, giving a total of 

 32173 miles of single railway, of which 2544 are laid down on the 

 common gauge, and 427 miles on the broad gauge. 



Table D shows the number of miles of single and double railway, 

 the stated number of miles of railway, and the number of miles of single 

 railway laid down with each of seven principal forms of rails, accord- 

 ing to the classification of Mr. Whishaw. 



Table E shows for 2271^ miles of single railway, the number of 

 miles of single and double railway, the total number of miles of rail- 

 way, and the number of miles of single railway, of each kind of rail, 

 with the total weight in tonS: It thus appears that rails of nearly 30 

 dittcrent weights are in use. 



Table F shows for 2271i miles of single railway, the number of 

 miles of single railway of each description of rails, with the weight in 

 tons, and the proportion per cent, of each class. From this it seems 

 that about a quarter or 510J miles of single railway have rails under 

 50 lb. weight. The total weight of rails for 2271i miles of single 

 railway is 204,412 tons, and if we take the remaining portion of rail- 

 ways at the same average, we shall have a total of 309,G04 tons of 

 iron consumed as rails.
