The greatest amount of lumber used for one project was the 37 miles of Snow Sheds, as mentioned above.
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.
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.
The CP's engines ranged in weight from 56,000 to 77,450 at the heaviest and they would average out at about 62-65,000 lbs.
The UPRR's engines were a little heavier, ranging from 54,500 to 93,300 lbs for an approximate average of about 75,000 lbs.
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.
Total engine weight would be about 10,000 tons or so.
But then there were the engines acquired by both companies from other railroads, and on infinitem.
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).
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?
I would think that [the above] estimate of approximately 200,000 tons of iron, just for the track, is as close as you will ever get without access to the original records scattered in archives across the country, and then it is doubtful they are even close to being complete.
