The 4073 or Castle Class are 4-6-0 steam locomotives of the Great Western Railway, built between 1923 and 1950. They were designed by the railway's Chief Mechanical Engineer, Charles Collett, for working the company's express passenger trains. They could reach speeds of up to 100 mph (160 km/h).
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 Louisville and Nashville Railroad, commonly called the L&N, was a Class I railroad that operated freight and passenger services in the southeast United States.
The Pennsylvania Railroad's class B6 was its most successful class of switcher locomotive, or as the PRR termed them "shifter". The PRR preferred the 0-6-0 wheel arrangement for larger switchers, whereas on other railroads the 0-8-0 gained preference. The PRR generally used 2-8-0s when larger power was required.
Early Electro-Motive Corporation switcher locomotives were built with Winton 201-A engines. A total of 175 were built between February 1935 and January 1939. Two main series of locomotives were built, distinguished by engine size and output: the straight-8, 600 hp (450 kW) 'S' series, and the V12, 900 hp (670 kW) 'N' series. Both were offered with either one-piece cast underframes from General Steel Castings of Granite City, Illinois, denoted by 'C' after the power identifier, and fabricated, welded underframes built by EMC themselves, denoted by 'W'. This gave four model series: SC, SW, NC and NW. Further developments of the 900 hp (670 kW) models gave model numbers NC1, NC2, NW1, and NW1A, all of which were practically indistinguishable externally from the others, as well as a pair of unique NW4 models for the Missouri Pacific Railroad and a solitary, twin-engined T transfer locomotive model built for the Illinois Central Railroad.
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 Wilmington and Western Railroad is a freight and heritage railroad in northern Delaware, operating over a former Baltimore and Ohio Railroad (B&O) branch line between Wilmington and Hockessin. The 10.2-mile (16.4 km) railroad operates both steam and diesel locomotives. It was added to the National Register of Historic Places as a national historic district in 1980. Wilmington & Western serves one customer for revenue service, and interchanges with CSX Transportation at Landenberg Junction, Delaware
The Atlanta, Birmingham and Coast Railroad was organized in 1926 to replace the bankrupt Atlanta, Birmingham and Atlantic Railway. The AB&C was controlled by the Atlantic Coast Line Railroad, which owned a majority of the stock. In 1944 it reported 763 million net ton-miles of revenue freight and 33 million passenger-miles; at the end of that year it operated 639 miles of road and 836 miles of track.
Southern Railway 4501 is a preserved Ms class 2-8-2 "Mikado" type steam locomotive built in October 1911 by the Baldwin Locomotive Works in Philadelphia, Pennsylvania, as the first of its wheel arrangement type for the Southern Railway (SOU). In July 1948, the locomotive was retired from the Southern Railway in favor of dieselization and was subsequently sold to the shortline Kentucky and Tennessee Railway (K&T) in Stearns, Kentucky, to haul coal trains.
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.
Reading Blue Mountain and Northern 425 is a 4-6-2 light "Pacific" type steam locomotive originally built in 1928 by the Baldwin Locomotive Works for the Gulf, Mobile & Northern Railroad. After the GM&N was consolidated into the Gulf, Mobile & Ohio in 1940, the locomotive was renumbered No. 580 and served in passenger service before being retired in 1950. The locomotive is currently owned and operated by the Reading & Northern, based out of Port Clinton, Pennsylvania in excursion service. At the end of 2022, No. 425 was taken out of service for its mandatory Federal Railroad Administration (FRA) 1,472-day inspection and overhaul.

Henry Roe Campbell was an American surveyor and civil engineer. Campbell contributed to American railroading and bridge-building in the first half of the 19th century. Campbell patented his 4-4-0 design in February 1836, just a few months before the patent law was changed to require that claims include proof of originality or novelty.
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.
Savannah and Atlanta 750, formerly Florida East Coast 80, is a 4-6-2 “Light Pacific” steam locomotive built in January 1910 by the American Locomotive Company (ALCO) of Schenectady, New York, originally for the Florida East Coast Railway (FEC) as No. 80. Throughout the 1930s, FEC had sold of several of their locomotives, with No. 80 being sold in 1935 to the Savannah and Atlanta Railway, where it was renumbered to 750. The locomotive pulled commuter passenger trains and occasional mixed freight trains for the S&A, until the railroad dieselized in the early 1950s. In 1962, the locomotive was donated to the Atlanta Chapter of the National Railway Historical Society, who began using the locomotive to pull occasional excursion trains. No. 750 was subsequently leased to the Southern Railway for use to pull trains for their new steam excursion program, and the lease ended in 1984. From 1985 to 1989, the locomotive pulled excursion trains for the New Georgia Railroad around Atlanta, until it was retired, due to firebox issues. As of 2022, No. 750 remains on static display inside the Southeastern Railway Museum in Duluth, Georgia.
