The ties varied in size, some as long as 10 feet and some as large as 8"x10" in size, depending if the track was being laid in the mountains or the deserts, on heavy or gentle grades, on curves or tangents (straight track). At one time the Central Pacific had as many as 25 Saw Mills in Truckee just milling lumber for the railroad which required as many as 40 trains to supply the front withties and timber– and they just managed to keep up with the track laying forces.Entire forests were cut back for miles from the line, some taking a hundred years or more to recover.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 ...' ...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?D., Harvard Economic Studies, 1908, states on page 256 that: " ... both principal and interest were paid in full."

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).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.can you imagine the labor of weighting 3 million, three hundred fifty five thousand, one hundred an seventy pounds of rail?
