Portola in Plumas County, California — The American West (Pacific Coastal)
Rail is designated by weight in pounds per yard. By the time the Western Pacific started construction in 1907, heavy mainlines used 85 to 100 pound rail, while industries, spurs and shortline railroads used rail as light as 40 pounds. Most of it was laid in 39' lengths which were bolted together. Today, the most common size is 136 pound, although rail as large as 152 pounds has been
While the Western Pacific was an early user of such trackwork innovations as concrete ties, it was fairly conservative in its rail. By the time of the Union Pacific merger in 1983, much of the Oakland to Salt Lake City mainline was laid with 115 pound bolted rail, the common type at the time. Many branches and sidings were still laid with rail as light as 65 pounds. The yard at the Western Pacific Railroad Museum, for instance, is mostly 65 pound rail. The railroad did explore welded rail, but its widespread use on WP lines would not occur until after the Union Pacific took over.
Today, most of the ex-WP mainline is 136 pound welded rail.

In May 1831, the first flanged T rail (also called "T-section") arrived in America from Britain and was laid into the Pennsylvania Railroad by Camden and Amboy Railroad. They were also used by Charles Vignoles in Britain. The first steel rails were made in 1857 by Robert Forester Mushet, who laid them at Derby station in England. Steel is a much stronger material, which steadily replaced iron for use on railway rail and allowed much longer lengths of rails to be rolled.
