A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
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).
Lima Locomotive Works was an American firm that manufactured railroad locomotives from the 1870s through the 1950s. The company took the most distinctive part of its name from its main shop's location in Lima, Ohio. The shops were located between the Erie Railroad main line, the Baltimore & Ohio's Cincinnati-Toledo main line and the Nickel Plate Road main line and shops.
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.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-6-6-2 is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and one pair of trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives, although some tank locomotive examples were also built. A Garratt locomotive or Golwé locomotive with the same wheel arrangement is designated 2-6-0+0-6-2 since both engine units are pivoting.
The 2-6-6-6 is an articulated locomotive type with two leading wheels, two sets of six driving wheels and six trailing wheels. Only two classes of the 2-6-6-6 type were built. One was the "Allegheny" class, built by the Lima Locomotive Works. The name comes from the locomotive's first service with the Chesapeake and Ohio Railway beginning in 1941, where it was used to haul loaded coal trains over the Allegheny Mountains. The other was the "Blue Ridge" class for the Virginian Railway. These were some of the most powerful reciprocating steam locomotives ever built, at 7,500 hp, and one of the heaviest at 386 tons for the locomotive itself plus 215 tons for the loaded tender.
Pere Marquette 1225 is a class "N-1" 2-8-4 "Berkshire" type steam locomotive built in October 1941 for the Pere Marquette Railway (PM) by Lima Locomotive Works (LLW) in Lima, Ohio. No. 1225 is one of two surviving Pere Marquette 2-8-4 locomotives, the other being 1223, which was on display at the Tri-Cities Historical Society near the ex-Grand Trunk Western (GTW) coaling tower in Grand Haven, Michigan, and both have the distinction of being the only surviving Pere Marquette steam locomotives left in preservation. No. 1225 was well known to be the basis for the locomotive used in the 2004 film The Polar Express, earning itself the nickname "The Real Polar Express."
Chesapeake & Ohio 614 is a class "J-3-A" 4-8-4 "Greenbrier" (Northern) type steam locomotive built in June 1948 by the Lima Locomotive Works in Lima, Ohio for the Chesapeake and Ohio Railway (C&O) as a member of the J-3-A class. As one of the last commercially built steam locomotives in the United States, the locomotive was built with the primary purpose of hauling long, heavy, high speed express passenger trains for the Chesapeake & Ohio Railway such as the George Washington and the Fast Flying Virginian. Retired from active service in the late 1950s, the 614 was preserved and placed on display at the B&O Railroad Museum in Baltimore, Maryland. Between 1979 and 1980, restoration work on the locomotive to operating condition took place and it was used for extensive mainline excursion service from the early 1980s until the late 1990s. Since 2011, the locomotive has been on display at the C&O Railway Heritage Center in Clifton Forge, Virginia.
Nickel Plate Road 765 is a class "S-2" 2-8-4 "Berkshire" type steam locomotive built for the New York, Chicago & St. Louis Railroad, commonly referred to as the "Nickel Plate Road". In 1963, No. 765, renumbered as 767, was donated to the city of Fort Wayne, Indiana, where it sat on display at the Lawton Park, while the real No. 767 was scrapped in Chicago in 1964.
A "Berkshire" type steam locomotive refers to a steam locomotive built with a 2-8-4 wheel configuration. The design was initially intended to improve on the USRA Heavy Mikado design (2-8-2), which was deemed to lack sufficient speed and horsepower. That was overcome by the inclusion of a larger, 100-square-foot (9.3 m2) firebox, requiring an extra trailing axle, giving the locomotive its distinctive 2-8-4 wheel arrangement.
The Chesapeake & Ohio Railway No. 1308 is an articulated 2-6-6-2 "Mallet" type steam locomotive built by Baldwin Locomotive Works in 1949. It was the next to the last Class 1 mainline locomotive built by Baldwin, closing out more than 100 years of production, a total of more than 70,000 locomotives. Its other surviving sister locomotive, No. 1309, has been restored to operation at the Western Maryland Scenic Railroad in Cumberland, Maryland.
The Hocking Valley Scenic Railway is a non-profit, 501c3, volunteer-operated tourist railroad attraction that operates out of Nelsonville, Athens County, Ohio. It is also located near the popular Hocking Hills State Park in nearby Hocking County. It uses former trackage of the Chesapeake & Ohio Railway, which was in turn originally Hocking Valley Railway trackage. The current operation was founded in 1972.
The Fort Wayne Railroad Historical Society (FWRHS) is a non-profit group in New Haven, Indiana that is dedicated to the restoration and operation of the ex-Nickel Plate Railroad's steam locomotive no. 765 and other vintage railroad equipment. Since restoration, the 765 was added to the National Register of Historic Places as no. 96001010 on September 12, 1996 and has operated excursion trains across the Eastern United States. In 2012, the FWRHS's steam locomotive no. 765 was added to the Norfolk Southern's 21st Century Steam program.
Chesapeake and Ohio Railway 2716 is a class "K-4" 2-8-4 "Kanawha" (Berkshire) type steam locomotive built in 1943 by the American Locomotive Company (ALCO) for the Chesapeake and Ohio Railway (C&O). While most railroads referred to these 2-8-4 type locomotives as Berkshires, the C&O referred to them as Kanawhas after the Kanawha River, which flows through West Virginia. Used as a dual service locomotive, No. 2716 and its classmates served the C&O in a variety of duties until being retired from revenue service in 1956.
The Chesapeake and Ohio Railway's K-4 class were a group of ninety 2-8-4 steam locomotives purchased during and shortly after World War II. Unlike many other railroads in the United States, the C&O chose to nickname this class "Kanawha", after the river in West Virginia, rather than "Berkshire", after the region in New England.
The Chesapeake and Ohio class H-8 was a class of 60 simple articulated 2-6-6-6 steam locomotives built by the Lima Locomotive Works in Lima, Ohio between 1941 and 1948, operating until the mid 1950s. The locomotives were among the most powerful steam locomotives ever built and hauled fast, heavy freight trains for the railroad. Only two units were preserved; Nos. 1601 and 1604.
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.
The Chesapeake and Ohio Greenbrier was a class of 12 4-8-4 "Greenbrier" type steam locomotives built by the Lima Locomotive Works between 1935 and 1948 and operated by the C&O. Like a handful of railroads, the C&O didn't name their 4-8-4s "Northerns", and instead went with the name "Greenbrier" after the Greenbrier Hotel in White Sulphur Springs, West Virginia, a major resort on the C&O mainline.
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 1947 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.
