Spearheaded by Chief Engineer William J. Wilgus and constructed under challenging conditions with no interruption of existing train service, Grand Central Terminal was a triumph of innovative engineering in the design of urban transportation centers. Its novel, two-level station, made possible by electric traction, streamlined both train and passenger movement by separating long-haul and suburban traffic and employing an extensive system of pedestrian ramps throughout the facility.

At the site of the first water pumping station providing water and sewage systems to the City of Erie in 1868, the Chestnut Street Pumping Station houses one of the largest steam engines, which pumped 20 million gallons a day. The triple-expansion steam reciprocating engine, which pumped water from the filter plant to the city reservoir, was typical of those used in municipal water pumping stations throughout the country during the late nineteenth and early twentieth centuries.

Spearheaded by Hugh Cooper, the Keokuk Dam & Power Plant served as a prototype for many future power plants. The project harnessed the hydropower of the Mississippi River, between Keokuk, Iowa and Hamilton, Illinois.

The crest of the dam is nearly a mile long. The dam structure features 119 arch spans between six-foot-thick piers and a 110-foot-wide pneumatic lock. Combined with the lock, the dam reduced travel time for steamboats by nearly two hours.
