 The Belle Isle gas turbine was installed in 1949 and was the first gas turbine built in the United States for the purpose of generating electric power. Its low cost and consistency aroused considerable interest in the electric utility industry, both here and abroad.

The Edger station was the first steam electric plant produced that could tolerate over 1000 psi of pressure. Initially conceived by Mr. Irving Edwin Moultrop, then Assistant Superintendent, Construction Bureau of the Edison Electric Illuminating Company of Boston. He guided his company and the electric utility industry on a major step forward into the higher-pressure range of 1,200 psi steam.

Duck Creek Aqueduct Covered Bridge

Duck Creek Aqueduct is a rare surviving example of a covered timber aqueduct. It was one of several similar structures on the Whitewater Canal, which operated between the Whitewater Valley and the Ohio River from 1839 to 1865. After being displaced by the railroad, the canal supplied hydraulic power for the industrial districts at Metamora and Brookville.

Doe River (Elizabethton) Bridge

Doe River Bridge is a fine example of a timber Howe truss, one of the most widely-used timber bridge designs. Built in 1884, this structure played an integral role in the development of the City of Elizabethton, Tennessee, and it is a rare example of a covered bridge that survives in an urban setting.

The original contract specified the unusual hip roof design, which resembles covered bridges in central Europe. The structure is very well-maintained and still carries automobile traffic. The bridge was restored in 2003.

Bunker Hill Covered Bridge

Bunker Hill Bridge is the only surviving Haupt truss bridge in the U.S. and one of only two surviving covered bridges in North Carolina. Patented in 1839, the Haupt truss featured diagonal braces spanning multiple panels, which was an attempt to eliminate the cross-strain found in lattice truss bridges. Although it was almost immediately eclipsed by the Howe truss and never reached the mainstream of covered bridge building, the Haupt truss is of interest for its association with Gen.

The Ashuelot Covered Bridge is located at the center of Ashuelot, NH. It is a Town lattice truss bridge, spanning the Ashuelot River in a roughly north-south orientation. It consists of two spans with a total length of 178 feet (54 m). The total width of the bridge is 29 feet (8.8 m), and has a central roadway and sidewalks (measuring 3'10" in width) on each side. The bridge rests on stone abutments and a central pier. The abutments have been reinforced with concrete since the bridge was built, and the central pier has been protected by a metal breakwater.

Ackley Bridge is an excellent example of a multiple kingpost truss and a noteworthy early example of covered bridge preservation efforts in the United States. Built in 1832 by Joshua Ackley (b.1805) and Daniel Clouse (b.1812), Ackley Bridge originally spanned Enslow’s Branch of Wheeling Creek between Greene County and Washington County in Pennsylvania, where it carried traffic for over a century.

The Titan is a 200-ton electrically driven hammerhead cantilever crane, the earliest survivor of this type. It is now all that remains of the once great John Brown Shipyard in Clydebank near Glasgow where many of the world's great ships were built. Designed and constructed by Sir William Arrol and Co. Ltd., Glasgow, Scotland, in 1907 the Titan set the standard for many more similar cranes to be erected worldwide. It has been restored and opened as a tourist attraction in 2007.

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.
