All rail ordered for the Central Pacific Railroad was by the metric ton, 2240 pounds per ton.

If the rail is 56 lb/yard, then the total rail weight is about 175 thousand tons (about a hundred tons of rail per mile).

To this you would need to add the weight of about 5,500 spikes and 1,408 bolts per mile, 900 tons of iron used in the construction of the Sierra snow sheds, plates, switches and sidings, iron hardware used in constructing wooden trestle bridges, 20-40 ton locomotives, cars, etc.

Other sources speak of "fifty-ton locomotives" and "two or three tons of spikes and fish plates" per mile.

For locomotive numbers and weights, also see the multi-page CPRR and UPRR locomotive lists.

See the discussion of "dollars per mile of track" including the question of exactly where do the Sierra Nevada mountains begin and end. Graves states that the 1887 Pacific RR Commission said the cost of construction from Sacramento City to Promontory, as of July, 1869 was $61,249,916.11; cash or cash equivalent was $32,397,135.58.
