As Weird Harold noted the good roads are already in place, and there is a steel bottle neck. Railroads use a lot of steel Let’s look at a mile of track laid with fifty-five pound to the yard rail, ties two feet on center, and in fact the same rail specified for the first transcontinental railroad in the 1863 Pacific Railroad Act. For a mile of track the rails weigh 86.43 tons in 352 thirty foot rails. Splice bars weigh (352 @ 29 lbs/ pair ÷ 2,000 lbs/ ton =) 5.104 tons. Nuts and bolts weigh (352 x 4 x 200lbs ÷ 259 ÷ 2,000 lbs =) 0.544 tons. Spikes weigh (5,632 lbs ÷ 2,000 lbs / ton =) 2.816 tons. Totaling the ironmongery we have 94.894 tons. I used two primary references to get these numbers to crunch. The Handlan-Buck Railroad, Miners, Machinists, and Lumber Mill Supplies catalog of 1918, Handlan-Buck Mfg. Co., Saint Louis, Missouri, pages 325-326, and Marshall Kirkman, Building and Repairing Railways, World Railway Publishing Company, London, © 1907, pages 680-681.
Note that locomotives and railroad cars will require even more. Here is the weight of materials in a steam locomotive John H. White Jr. American Locomotives, an Engineering History 1830-1880, © 1968, Johns Hopkins Press, Baltimore, Maryland, pages 474 and 476 quotes the following totals for various materials use in an 1865 Hinkley Locomotive Works 4-4-0 with sixty inch drivers and 15 x 24 inch cylinders. Note that the weights are the finished parts not the rough castings or rough bar stock weight. I calculated following totals. The engine has: brass 1,948 lbs., wood 2,718 lbs, wrought iron 29,627 lbs., and cast iron 19,785 lbs. used in 4,904 parts. The tender has: brass 83 lbs., wood 3,118 lbs., wrought iron 8,330 lbs., and cast iron 6,987 lbs. used in 1,366 parts. Total weight engine 54,078 lbs., total weight tender 18,518 lbs, and total weight engine and tender is 72,596 lbs. spread over a total of 6,270 parts. Thus the locomotive and tender contain: brass 2,031 lbs. 1.0155 tons wood 5,836 lbs or 2.918 tons, wrought iron 37,957 lbs or 18.9785 tons, cast iron 67,772 lbs. or 13.386 tons. Substitute steel for wrought iron and you get the idea. And this is to build a light Civil War Era railroad!
