Beneath this plaque the first transcontinental railroad traversed the mighty Sierra Nevada range. The 1659 foot long summit tunnel took over 15 months of Chinese muscle and sweat to build. The Chinese painstakingly hand drilled, then blasted the granite rock with black powder and newly invented nitroglycerin. A vertical shaft took 85 days to complete and allowed tunnel construction to proceed from the center as well as from the portals. The most difficult obstacle facing the Central Pacific Railroad was overcome when the tunnel was completed in August 1867. The first passenger train passed through the tunnel on June 18, 1868. The last train went through in 1993.
