One hundred tons per mile included the main line and all the side track, incidental uses and waste.
1004 reports that final payment to the government was organized by a commission appointed by an 1898 act of congress, determined to be ,812,715.48 on Feb.1, 1899, and that the complex transaction was completed on February 1, 1909 when the last of the government debt was duly paid.How much iron and lumber was used in the construction of the transcontinental railroad?That would requireagreat deal of research to even estimate. This should be an easy one to develop a reasonable estimate as there was an average of about 2,500 wood ties per mile over the entire 1,776 miles of the transcontinental railroad.The average size of the tie was 6"x8" x 8 feet long. I'll leave that one for you to figure out the Board Feet required. Then there were the side tracks which amounted to about 10% of the mainline track.
(Not sure if the weights of locomotives listed are shipping weight or maximum track loading including water.) If you estimate from the available data that about 21,000 miles of track were put in place during the 1860's in the U. and that the amount of iron used is proportional to the track miles built, then the percent of iron used in building the transcontinental railroad (compared to all U. railroads' iron use during 1860's construction) is about: (1,776/21,000)*100 = 8.5% According to Galloway: "The number of ties varied from 2,260 to 2,640 per mile, depending upon alignment and grade. The total completed length of the sheds and galleries was about thirty-seven miles, the building of which consumed 65,000,000 feet board measure of lumber and 900 tons of bolts, spikes, and other iron." of rail was accounted for, as shown by a letter from Collis P.
