QuoteOn that [line] extending between Newcastle and Berwick, 66.8 miles of double way, the iron rails laid down in 1847 weighed 65 pounds per yard. Renewals commenced in 1855 and terminated in 1867. In these the weight was increased to 82 pounds per yard. The maximum duration of the 65-pound rails was 21 years and the minimum 8 years, the average being 12.8 years. Mr. T. E. Harrison stated in 1867 that on 700 miles of permanent way of the North-Eastem Railway the average duration of the last complete set of rails was found to be about 15.5 years; and some which were laid down in 1834 were still in use.
