In the early 1900s, Union Station was the hub of passenger railroad traffic in the central United States. It was one of the first stations to serve as a centralized terminal for multiple railroad lines. It originally served 22 rail lines; 13 from the east and nine from the west.

Tunkhannock Viaduct
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1910-1919 DateCreated: 1915 Tunkhannock Creek Nicholson State: PA Zip: 18446 Country: USA Website: http://www.asce.org/Project/Tunkhannock-Viaduct/ Creator: Cohen, Abraham Burton, Delaware, Lackawanna and Western Railroad

This majestic viaduct was built during the golden age of railroading. It was at the western end of a major readjustment in grade and alignment of the Erie-Lackawanna Railroad, and had double tracks to carry the trains across the valley of Tunkhannock Creek. The Hallstead cutoff (between Scranton, Pennsylvania and Hallstead, New Jersey) reduced passenger travel time by 20 minutes, and freight travel time by over an hour.

Central Pacific Railroad
Society: ASCE Main Category: Civil Sub Category: Roads & Rails Era: 1860-1869 DateCreated: 1863-1869 Western America Ogden State: UT Zip: Country: USA Website: http://www.asce.org/project/central-pacific-railroad/ Creator: Judah, Theodore , Crocker, Charles

Central Pacific Railroad served as the Western terminus of America's first transcontinental railroad, passing through the formidable Sierra Nevada Mountains. In all, 15 tunnels were blasted through solid granite. 

Thousands of Chinese from Kwantung Province were recruited by Central Pacific Railroad Company and became known for their diligence and hard work. In the second year of construction, nine out of ten workers on the CPRR were Chinese.

Tehachapi Pass Railroad Line
Society: ASCE Main Category: Civil Sub Category: Roads & Rails Era: 1870-1879 DateCreated: 1876 Walong State: CA Zip: Country: USA Website: http://www.asce.org/Project/Tehachapi-Pass-Railroad-Line/ Creator: Harris, J. B. , Southern Pacific Railroad

The Tehachapi Pass Railroad Line was cut through solid and decomposed granite by about 3,000 Chinese laborers using nothing more than picks, shovels, horse drawn carts, and blasting powder. This line, which rises from the San Joaquin Valley and through the Tehachapi Mountains, originally included 18 tunnels, ten bridges and several water towers to accommodate the steam locomotives. Completed in less than two years, it was part of the final line of the first railroad to connect San Francisco with Los Angeles.

Rockville Stone Arch Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1900-1909 DateCreated: 1902 Susquehanna River Marysville State: PA Zip: 17053 Country: USA Website: http://www.asce.org/Project/Rockville-Stone-Arch-Bridge/ Creator:

The third bridge built on the same site to carry railroad tracks across the Susquehanna River just north of Harrisburg, Pennsylvania, the Rockville Stone Arch Bridge, at 3,820 feet long and 52 feet wide, is believed to be the longest and widest stone-arch railroad bridge in the world. A central link in rail travel between New York City and Pittsburgh, the Rockville Stone Arch Bridge accommodates four lines of railroad tracks, today serving both the Norfolk Southern and Amtrak lines.

Quebec Bridge
Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1910-1919 DateCreated: 1917 Quebec Bridge Quebec City State: Quebec Zip: G1K 4J9 Country: Canada Website: http://www.asce.org/Project/Quebec-Bridge/ Creator: McLure, Norman , Cooper, Theodore

The bridge is immense, not only in length and weight but in width. At 67 feet wide, it can accommodate two sets of railway tracks, two sets of streetcar tracks and two roadways.

It took three tries and cost 89 lives, but the city of Quebec was determined to compete with provincial rival Montreal for commercial rail traffic in the late 19th century. The solution was a rail bridge across the St. Lawrence River requiring a single cantilever span 1,800 feet long - the longest ever attempted.

Moffat Tunnel

Known as "the highest and lowest holing in history," the tunnel bored through the Rockies at an elevation of 9,200 feet, 2,800 feet below the surface. Eight hundred men worked around the clock for 3 1/2 years, moving 3 billion pounds of rock.

High Bridge

In the 1850s, the Lexington and Danville Railroad began building a suspension bridge over the Kentucky River. The bridge was designed by John A Roebling. Due to unforeseen increases in train loads, the Roebling bridge was never completed. The High Bridge would then be built 20 years later on the existing foundations.

Crozet's Blue Ridge Tunnel
Society: ASCE Main Category: Civil Sub Category: Roads & Rails, Transportation, Tunnels Era: 1850-1859 DateCreated: 1858 Blue Ridge Railroad Waynesboro State: VA Zip: 22980 Country: USA Website: http://www.asce.org/People-and-Projects/Projects/Landmarks/Crozet-s-Blue-Ridge-Tunnel/ Creator: Crozet, Claudius

One of four single-track tunnels built by the Blue Ridge Railroad, the 4,273-foot Crozet Tunnel was constructed at a time when hand drills, pickaxes, and black powder amounted to state-of-the-art tunneling technology. At the time of its completion, it was the longest railroad tunnel in the world. Envisioned and built by Claudius Crozet, a French-born educator and civil engineer, the tunnel remains a testament to his belief in advancing rail transportation even when faced with numerous difficulties.

Southern Pacific #4294 Cab-in-Front Steam Locomotive
Society: ASME Main Category: Mechanical Sub Category: Rail Transportation Era: 1940-1949 DateCreated: 1944 California State Railroad Museum Sacramento State: CA Zip: 95814 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-m-z/rail-transportation---1/-62-southern-pacific--4294-cab-in-front-steam-loco, https://www.asme.org/getmedia/4527cb4e-6984-4c88-b513-c3daf7dd5679/62-Southern-Pacific-4294-Cab-in-Front-Steam-Loco.aspx Creator: Baldwin Locomotive Works, Southern Pacific Railroad

The articulated wheel-base steam locomotive represents the final phase of steam locomotive development in size and power. The cab-in-front feature was widely used by the Southern Pacific Railroad beginning in 1909 to alleviate smoke and heat problems for locomotive personnel en route through tunnels and snow sheds. This locomotive, built by the Baldwin Locomotive Works, operated between 1944 and 1956 before being displaced by a diesel-electric locomotive.
