What Is Standard Gauge?
Railroads did not start out being built to a single standard gauge. In North America the early lines started in the 1830s were seen as local affairs, often built to connect a port with the inland area around it. Some railroads were built to standard gauge because the locomotives were purchased from England, and that was the most common English gauge. Others chose a gauge they thought more logical, such as 4' 10," 5,' 5' 6" (used on most Canadian lines), or 6,' and had locomotives and cars built to this dimension.
The Pacific Railroad of Missouri, which built its main line and the tunnel on this site in 1851-53, used 5' 6" gauge. The Mississippi River,
There were four major factors in 4' 8 ½" becoming recognized as the standard gauge by 1865. First it was the most common gauge in the US, used by 210 railroad companies, having 17,712 miles of track, 53.3% of the total mileage in use. A second was that 5' gauge, the second most common, with 21.9% of track use, was only found in the South, which was fighting the Union during the Civil War (1861-65) removing it from consideration. Third was the need for more efficient movement of troops and freight during the Civil War, which made some northern lines add a third rail so trains of two gauges could use their track. Finally, in 1863 Congress selected 4' 8 ½" as the gauge for the Transcontinental Railroad, establishing it as the preferred gauge.
The Pacific Railroad of Missouri converted to standard gauge in 1869, and most Canadian lines were converted in 1872-73. It wasn't until 1886 that the conversion was complete on
