The Shay locomotive is a geared steam locomotive that originated and was primarily used in North America. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive. Although the design of Ephraim Shay's early locomotives differed from later ones, there is a clear line of development that joins all Shays. Shay locomotives were especially suited to logging, mining and industrial operations and could operate successfully on steep or poor quality track.
H.K. Porter, Inc. (Porter) manufactured light-duty railroad locomotives in the US, starting in 1866. The company became the largest producer of industrial locomotives, and built almost eight thousand of them. The last locomotive was built in 1950, but the company continues to produce industrial equipment to this day.
Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles and no trailing wheels. This arrangement is commonly called a Mogul.
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s Consolidation, the name of the first 2-8-0.
The McKeen Motor Car Company of Omaha, Nebraska, was a builder of internal combustion-engined railroad motor cars (railcars), constructing 152 between 1905 and 1917. Founded by William McKeen, the Union Pacific Railroad's Superintendent of Motive Power and Machinery, the company was essentially an offshoot of the Union Pacific and the first cars were constructed by the UP before McKeen leased shop space in the UP's Omaha Shops in Omaha, Nebraska. The UP had asked him to develop a way of running small passenger trains more economically and McKeen produced a design that was ahead of its time. Unfortunately, internal combustion engine technology was not and the McKeen cars never found a truly reliable powerplant.
The Virginia and Truckee Railroad is a privately owned heritage railroad, headquartered in Virginia City, Nevada. Its private and publicly owned route is 14 miles (23 km) long. When first constructed in the 19th century, it was a commercial freight railroad which was originally built to serve the Comstock Lode mining communities of northwestern Nevada.
The St. Louis–San Francisco Railway, commonly known as the "Frisco", was a railroad that operated in the Midwest and South Central United States from 1876 to April 17, 1980. At the end of 1970, it operated 4,547 miles (7,318 km) of road on 6,574 miles (10,580 km) of track, not including subsidiaries Quanah, Acme and Pacific Railway and the Alabama, Tennessee and Northern Railroad; that year, it reported 12,795 million ton-miles of revenue freight and no passengers. It was purchased and absorbed into the Burlington Northern Railroad in 1980. Despite its name, it never came close to San Francisco.
Under the Whyte notation for the classification of steam locomotives, 0-4-2 represents the wheel arrangement with no leading wheels, four powered and coupled driving wheels on two axles and two trailing wheels on one axle. While the first locomotives of this wheel arrangement were tender engines, the configuration was later often used for tank engines, which is noted by adding letter suffixes to the configuration, such as 0-4-2T for a conventional side-tank locomotive, 0-4-2ST for a saddle-tank locomotive, 0-4-2WT for a well-tank locomotive and 0-4-2RT for a rack-equipped tank locomotive. The arrangement is sometimes known as Olomana after a Hawaiian 0-4-2 locomotive of 1883.
The Durango and Silverton Narrow Gauge Railroad, often abbreviated as the D&SNG, is a 3 ft (914 mm) narrow-gauge heritage railroad that operates on 45.2 mi (72.7 km) of track between Durango and Silverton, in the U.S. state of Colorado. The railway is a federally-designated National Historic Landmark and was also designated by the American Society of Civil Engineers as a National Historic Civil Engineering Landmark in 1968.
The BHP Nevada Railroad was a shortline railroad that operated in Nevada from 1996 to 1999. BHP acquired the line from Nevada Northern Railway. Constructed by Utah Construction Company in 1908, the railroad hauled copper ore concentrate from BHP's concentrator at Riepetown to Shafter, Nevada. At Shafter the railroad interchanged with the Union Pacific and the ore continued to BHP's smelter at San Manuel, Arizona. BHP is an Australian-based company that took over Magma Copper, the owner of the Robinson Mine at Ruth, Nevada, in January 1996. The line ran south from a connection with the Union Pacific at Shafter to Ely.
The Lake Superior and Ishpeming Railroad, is a U.S. railroad offering service from Marquette, Michigan, to nearby locations in Michigan's Upper Peninsula. It began operations in 1896. The LS&I continues to operate as an independent railroad from its headquarters in Marquette.
The Oregon, Pacific and Eastern Railway was an Oregon-based short line railroad that began near Eugene as the Oregon and Southeastern Railroad (O&SE) in 1904. O&SE's line ran 18 miles (29 km) along the Row River between the towns of Cottage Grove and Disston. The Oregon, Pacific & Eastern Railway Company incorporated in 1912, purchased the physical assets of the O&SE two years later, and shortened their total trackage to operate 16.6 miles (26.7 km) from an interchange yard with the Southern Pacific Railroad at Cottage Grove, east to a 528' x 156' turnaround loop at Culp Creek. The last of this track was closed and scrapped in 1994, and ownership of its abandoned right of way property was later reverted to the state of Oregon to become one of the first-ever Government/Private Sector cooperative partnership Rails to Trails programs in the US, forming the Row River National Recreation Trail. A successor corporation now operates a narrow-gauge line at Wildlife Safari.
The Colorado and Southern Railway was an American Class I railroad in the western United States that operated independently from 1898 to 1908, then as part of the Chicago, Burlington and Quincy Railroad until it was absorbed into the Burlington Northern Railroad in 1981.

The Adobe Mountain Desert Park a.k.a. "The Railroad Park" is a park complex that houses the Sahuaro Central Railroad Heritage preservation Society, Sahuaro Central Railroad Museum, Arizona Model Railroading Society, and the Maricopa Live Steamers. The approximately 160-acre Adobe Mountain Desert Railroad Park is located south of Pinnacle Peak Road on 43rd Avenue in the City of Glendale, Arizona.
Tremont and Gulf Railroad No. 30 is a preserved class 30 2-8-2 "Mikado" steam locomotive built by the Baldwin Locomotive Works in 1917 for the Tremont and Gulf Railroad. It was used by the T&G for hauling freight trains in branch lines throughout the state of Louisiana until 1954, when it was sold to the Magma Arizona Railroad and renumbered 7. There, the locomotive was used for hauling smaller freight trains in Southern Arizona, until its retirement in 1968. Afterwards, it continued to be sold to various owners and groups, until it was purchased by the Texas State Railroad in 1974. It was restored to operating condition and used to pull tourist excursion trips between Rusk and Palestine, Texas as No. 400 from 1978 to 2002. Since 2014, the locomotive has been back under steam on the TSRR as MAA No. 7, and then it was reverted to T&G No. 30 in 2017. It is still operational as of 2023.
