A Mallet locomotive is a type of compound articulated steam locomotive, invented by the Swiss engineer Anatole Mallet (1837–1919).
A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing its fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board are called tank locomotives or tank engines.
The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1962.
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.
The EMD E8 is a 2,250-horsepower (1,678 kW), A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. A total of 450 cab versions, or E8As, were built from August 1949 to January 1954, 447 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1949 to January 1954, all for the U.S. The 2,250 hp came from two 12 cylinder model 567B engines, each driving a generator to power the two traction motors on one truck. The E8 was the ninth model in the line of passenger diesels of similar design known as EMD E-units. Starting in September 1953, a total of 21 E8As were built which used either the 567BC or 567C engines.
The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation between December 1938 and November 1953. Final assembly was at EMD's plant at LaGrange (McCook) Illinois. The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC and SW. The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, with a gap in production between March 1943 and September 1945 due to World War II.
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 November 21, 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. In 1980 it was purchased by and absorbed into the Burlington Northern Railroad. Despite its name, it never came close to San Francisco.
The Royal Hudsons are a series of semi-streamlined 4-6-4 "Hudson" type steam locomotives formerly owned and operated by the Canadian Pacific Railway (CPR) and built by Montreal Locomotive Works (MLW). The engines were built in 1937. In 1939, King George VI allowed the CPR to use the term after Royal Hudson number 2850 transported the royal train across Canada with no need of replacement. These locomotives were in service between 1937 and 1960. Four of them have been preserved. No. 2839 was used to power excursions for the Southern Railway Steam Program between 1979 and 1980. No. 2860 was used for excursion service in British Columbia between 1974 and 1999, then again between 2006 and 2010.
The North Carolina Transportation Museum is a museum in Spencer, North Carolina. It is a collection of automobiles, aircraft, and railway vehicles. The museum is located at the former Southern Railway's 1896-era Spencer Shops and devotes much of its space to the state's railroad history. The museum has the largest collection of rail relics in the Carolinas. Its Back Shop building of nearly three stories high is notable for its size, two football fields long.
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 miles (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 Arkansas and Missouri Railroad is a Class III short-line railroad headquartered in Springdale, Arkansas.
Southern Pacific 2472 is a P-8 Class 4-6-2 heavy "Pacific" type steam locomotive built by the Baldwin Locomotive Works for the Southern Pacific Railroad (SP) in 1921. No. 2472 is one of three surviving Southern Pacific P-8 class 4-6-2 Pacific locomotives, the other two being Nos. 2467 and 2479. The 4-6-2 designation means it has four leading wheels, six driving wheels, and two trailing wheels. The locomotive was used by the Southern Pacific Railroad to haul passenger trains until being retired in 1957. The locomotive was then donated to San Mateo County and placed on static display at the San Mateo County Fairgrounds. After being restored to operational condition in the early 1990s, the locomotive would pull excursion trains on the Niles Canyon Railway until being retired in 2015. The No. 2472 was then moved to the Northwest Pacific Railroad, where it is as of 2023, undergoing its Federal Railroad Administration (FRA) mandated 1,472 day inspection and overhaul.
The New Hope Valley Railway is a heritage railroad in Bonsal, North Carolina operated by the North Carolina Railway Museum, Inc., an all-volunteer, nonprofit, and tax exempt educational and historical organization.
An oil burner engine is a steam engine that uses oil as its fuel. The term is usually applied to a locomotive or ship engine that burns oil to heat water, to produce the steam which drives the pistons, or turbines, from which the power is derived.
The 5-mile (8.0 km) Reader Railroad was a tourist-only railroad operating in Reader, Arkansas from 1973 to 1991. As a 23-mile (37 km) common carrier prior to May 1973, it was the last all steam locomotive-powered, mixed train railroad operating in North America. It operated trackage in Ouachita County and Nevada County, Arkansas. The five mile tourist railroad operated until 1991, when it could not meet the new federal safety regulations.
Southern Railway 630 is a 2-8-0 "Consolidation" type steam locomotive built in February 1904 by American Locomotive Company (ALCO) of Richmond, Virginia for the Southern Railway (SOU) as a member of the Ks-1 class. It was primarily assigned to haul freight trains on the Murphy Branch between Asheville and Murphy, North Carolina until its retirement in the 1950s. No. 630, along with sister locomotive No. 722, were sold to the East Tennessee and Western North Carolina Railroad (ET&WNC) to be served as switchers.
Southern Railway 722 is a class "Ks-1" 2-8-0 "Consolidation" type steam locomotive built in September 1904 by the Baldwin Locomotive Works to run on the Murphy Branch, where it hauled freight trains between Asheville and Murphy, North Carolina for the Southern Railway (SOU). In 1952, it was purchased by the East Tennessee and Western North Carolina Railroad (ET&WNC), alongside its sister locomotive No. 630, where they were served as switchers around Johnson City and Elizabethton, Tennessee.
The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings.
Norfolk and Western 611, also known as the "Spirit of Roanoke" and the "Queen of Steam", is the only surviving example of Norfolk and Western's (N&W) class J 4-8-4 type "Northern" streamlined steam locomotives. Built in May 1950 at N&W's Roanoke Shops in Roanoke, Virginia, it was one of the last mainline passenger steam locomotives built in the United States and represents a pinnacle of American steam locomotive technology.
The Chicago and North Western R-1 class was a class of 325 4-6-0 "Ten-Wheeler" steam locomotives built by the Schenectady Locomotive Works, the American Locomotive Company, and the Baldwin Locomotive Works from 1901 to 1908. The R-1 locomotives were so large and so heavy that the Chicago and North Western (C&NW) Railroad had to extensively rebuild their trackage, bridges, tunnels, turntables, and enginehouses to accommodate them.
