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).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.rails, equal to 3,384,360 pounds.' but when he weighed those rails ' ...they weigh 3,355,170 pounds-which is 29,190 pounds less than your invoice ...' ...
The first approximately 112 miles of railvaried in weight from60 to 66 lb pattern, that is 60 to 66 lbsper lineal yard.
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?
All rail ordered for the Central Pacific Railroad was by the metric ton, 2240 pounds per ton.
After the 112th mile the rail was reduced to a 56lb. The rail requirements were usually calculated by the men who ordered it and by the men who installed it as requiring an average of 100 tons per mile, that was the way it was measured as it was impractical to measure by the foot.
