All rail ordered for the Central Pacific Railroad was by the metric ton, 2240 pounds per ton.
Some other major uses for lumber: There were many, many wooden trestles, most of them were huge and they required an enormous amount of lumber.(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.Huntington, in New York, dated 1873, to a supplier of rail, The Pennsylvania Iron Co., in Danville, Pennsylvania. Huntington says, in part that he contracted to buy ' ...One hundred tons per mile included the main line and all the side track, incidental uses and waste.Using that method of measurement the Central Pacific railroads 690 miles of track would have been approximately 69,000 (metric tons 2240#) tons of rail.About 200,000 net tons of iron total were used just for building the railroad from Omaha to Sacramento [at 2000 lbs/net ton, the modern useage, also called the short ton; the metric ton = 1000 kg ].
Details, at 60 lb/yard (per single rail) single track from Omaha to Sacramento: 1776 miles x 60 lb/yard x 5280 feet/mile x 1/3 yards/feet x 2 rails x 1/2000 ton/lb = (1776*60*5280*2)/(3*2000) = 187,546 tons of iron.D., Harvard Economic Studies, 1908, states on page 256 that: " ... both principal and interest were paid in full." Regarding the CPRR and Western Pacific RR, Tutorow, p.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.Not a scientific way to calculate but as close as you will ever get for just the rail.I can imagine that the Union Pacific's requirement was about the same so — for the total mileage of the transcontinental railroad of 1776 miles required 177,600 tons (metric tons) of rail for the track alone. more that a standard 2000 lb ton andthat if you reported the railtonnageat a 2,000 lb./ton the total rail weight alone would weigh198,912 tons of iron rail. Just remember that in the 1860's that rail was measured by the metric ton but bolts, spikes and rail fastenings were measured by the standard 2,000 lb. Then you would have to add the weight of spikes bolts, rail chairs, fish plates (rail fastenings).Total engine weight would be about 10,000 tons or so.
