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.
A Mallet locomotive is a type of compound articulated steam locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919).
A 2-8-8-4 steam locomotive, under the Whyte notation, has two leading wheels, two sets of eight driving wheels, and a four-wheel trailing truck. The type was generally named the Yellowstone, a name given it by the first owner, the Northern Pacific Railway, whose lines ran near Yellowstone National Park. Seventy-two Yellowstone-type locomotives were built for four U.S. railroads.
Under the Whyte notation for the classification of steam locomotives, 4-8-4 represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern.
Under the Whyte notation, a 2-8-4 is a steam locomotive that has two unpowered leading wheels, followed by eight coupled and powered driving wheels, and four trailing wheels. This locomotive type is most often referred to as a Berkshire, though the Chesapeake and Ohio Railway used the name Kanawha for their 2-8-4s. In Europe, this wheel arrangement was mostly seen in mainline passenger express locomotives and, in certain countries, in tank locomotives.
The Western Maryland Railway was an American Class I railroad (1852–1983) that operated in Maryland, West Virginia, and Pennsylvania. It was primarily a coal hauling and freight railroad, with a small passenger train operation.
The Western Maryland Scenic Railroad (WMSR) is a heritage railroad based in Cumberland, Maryland, that operates passenger excursion trains and occasional freight trains using both steam and diesel locomotives over ex-Western Maryland Railway (WM) tracks between Cumberland and Frostburg.

The Lake Superior and Ishpeming Railroad, is a Class III railroad 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 Atchison, Topeka and Santa Fe Railway's 3460 class comprised six 4-6-4 "Super Hudson" type steam locomotives built in 1937 by the Baldwin Locomotive Works for service between La Junta, Colorado and Chicago, Illinois, a fairly flat division of the railroad suited for the 4-6-4 type. They were substantially larger than the road's earlier 3450 class locomotives, and all were built oil-fired, although in a manner that would allow for easy conversion to coal firing. All were fitted with SKF roller bearings on every axle.
The Cumberland and Pennsylvania Railroad (C&P) was an American railroad which operated in Western Maryland. Primarily a coal hauler, it was owned by the Consolidation Coal Company, and was purchased by the Western Maryland Railway (WM) in 1944.
The Eckhart Branch Railroad was a railroad that operated in the Cumberland, Maryland area in the 19th century.
The Cumberland Valley Railroad was an early railroad in Pennsylvania, United States, originally chartered in 1831 to connect with Pennsylvania's Main Line of Public Works. Freight and passenger service in the Cumberland Valley in south central Pennsylvania from near Harrisburg to Chambersburg began in 1837, with service later extended to Hagerstown, Maryland, and then extending into the Shenandoah Valley to Winchester, Virginia. It employed up to 1,800 workers.
Nickel Plate Road 759 is a class "S-2" 2-8-4 "Berkshire" type steam locomotive built in 1944 by the Lima Locomotive Works in Lima, Ohio as a member of the S-2 class for the New York, Chicago & St. Louis Railroad, commonly referred to as the "Nickel Plate Road". Built as a fast freight locomotive, No. 759 served the Nickel Plate until being retired in 1959 and placed into storage. In 1965, No. 759 was purchased by F. Nelson Blount for display in his Steamtown, U.S.A. collection in North Walpole, New Hampshire. The locomotive was restored to operating condition in 1967 by New York commodity broker Ross Rowland for use in hauling his Golden Spike Centennial Limited, a special commemorative train that celebrated the 100th anniversary of the completion of the Transcontinental Railroad in 1969. Afterwards, No. 759 pulled numerous excursions for Ross Rowland and Steamtown until being retired once more and placed back on display in 1977. As of 2023, the locomotive remains on static display at the Steamtown National Historic Site in Scranton, Pennsylvania, and sibling engine No. 765 continues to operate in mainline excursion service.
The Reading T-1 was a class of 4-8-4 "Northern" type steam locomotives owned by the Reading Company. They were rebuilt from thirty "I-10sa" class 2-8-0 "Consolidation" type locomotives between 1945 and 1947. Out of the thirty rebuilt, four survive in preservation today, those being numbers 2100, 2101, 2102, and 2124.
The Western Maryland K-2 was a class of 9 4-6-2 "Pacific" type steam locomotives built by the Baldwin Locomotive Works in 1912 and operated by the Western Maryland Railway until the early 1950s.
Western Maryland Scenic Railroad No. 734, also known as Mountain Thunder, is an SC-1 class 2-8-0 “Consolidation” type steam locomotive originally built by the Baldwin Locomotive Works in 1916 for the Lake Superior and Ishpeming Railroad (LS&I) as No. 18. It was renumbered to 34 in 1925. No. 34 was used to pull heavy iron ore trains for the LS&I, until it was retired in 1961. The locomotive was subsequently sold to the Marquette and Huron Mountain Railroad, where it was stored in a sideline alongside other LS&I steam locomotives. In 1971, No. 34 was sold to the Illinois Railway Museum for static display.
The Louisville and Nashville M-1 was a class of forty-two 2-8-4 steam locomotives built during and after World War II as dual-service locomotives. They were nicknamed "Big Emmas" by crews and were built in three batches between 1942 and 1949.
Chesapeake and Ohio No. 490 is the sole survivor of the L-1 class 4-6-4 "Hudson" type steam locomotives. It was built by Alco's Richmond works in 1926 as an F-19 class 4-6-2 "Pacific" type to be used to pull the Chesapeake and Ohio's secondary passenger trains. It was eventually rebuilt in 1946 to become a streamlined 4-6-4 for the C&O's Chessie streamliner. After the Chessie was cancelled, No. 490 remained in secondary passenger service, until it was retired in 1953. It spent several years in storage in Huntington, West Virginia, until 1968, when it was donated to the B&O Railroad Museum in Baltimore, Maryland. It remains on static display at the museum, as of 2023.

It eventually became famous for pulling multiple mainline excursion trains throughout the state of Pennsylvania under the ownership of George Hart. It was sold to the Strasburg Rail Road in 1995, who had an initial plan to rebuild it to pull their own tourist trains. As of 2024, No. 972 is stored outdoors and disassembled in the Strasburg Rail Road's yard.
