Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement, particularly in the United Kingdom. Notable German locomotives of this type include the war locomotives of Class 52.
John Bull is a historic British-built railroad steam locomotive that operated in the United States. It was operated for the first time on September 15, 1831, and became the oldest operable steam locomotive in the world when the Smithsonian Institution ran it under its own steam in 1981. Built by Robert Stephenson and Company, it was initially purchased by and operated for the Camden and Amboy Railroad, the first railroad in New Jersey, which gave it the number 1 and its first name, "Stevens". The C&A used it heavily from 1833 until 1866, when it was removed from active service and placed in storage.
The Pennsylvania Railroad (PRR) K4 4-6-2 "Pacific" was its premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957.
The M1 was a class of steam locomotive of the Pennsylvania Railroad (PRR). It was a class of heavy mixed-traffic locomotives of the 4-8-2 "Mountain" arrangement, which uses four pairs of driving wheels with a four-wheel guiding truck in front for stability at speed and a two-wheel trailing truck to support the large firebox needed for sustained power. Although built for both passenger and freight work, they spent most of their service lives hauling heavy high-speed freight trains. Many PRR men counted the M1 class locomotives as the best steam locomotives the railroad ever owned.
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.
The Railroad Museum of Pennsylvania is a railroad museum in Strasburg, Lancaster County, Pennsylvania.
The Strasburg Rail Road is a heritage railroad and the oldest continuously operating standard-gauge railroad in the western hemisphere, as well as the oldest public utility in the Commonwealth of Pennsylvania. Chartered in 1832, the Strasburg Rail Road Company is today a heritage railroad offering excursion trains hauled by steam locomotives on 4.02 mi (6.47 km) of track in Pennsylvania Dutch Country, as well as providing contract railroad mechanical services, and freight service to area shippers. The railroad's headquarters are outside Strasburg, Pennsylvania.
The Pennsylvania Railroad DD1 was a class of boxcab electric locomotives built by the Pennsylvania Railroad. The locomotives were developed as part of the railroad's New York Tunnel Extension, which built the original Pennsylvania Station in New York City and linked it to New Jersey via the North River Tunnels. The Pennsylvania built a total of 66 locomotives in its Altoona Works; they operated in semi-permanently coupled pairs. Westinghouse supplied the electrical equipment.
Class D16 on the Pennsylvania Railroad was their final development of the 4-4-0 "American" type of steam locomotive. A total of 429 of these locomotives were built at the PRR's Juniata Shops, spread across five subclasses; some had 80 in (2,030 mm) diameter driving wheels for service in level territory, while others had 68 in (1,730 mm) drivers for mountainous terrain. In the pre-1895 scheme, these locomotives were second class L.
Class E6 on the Pennsylvania Railroad was the final type of 4-4-2 "Atlantic" locomotive built by the railroad, and second only to the Milwaukee Road's streamlined class A in size, speed and power. Although quickly ceding top-flight trains to the larger K4s Pacifics, the E6 remained a popular locomotive on lesser services and some lasted to the end of steam on the PRR. One, #460, called the Lindbergh Engine, is preserved at the Railroad Museum of Pennsylvania. It was moved indoors to begin preparations for restoration on March 17, 2010. On January 10, 2011, PRR #460 was moved to the museum's restoration shop for a two- to three-year project, estimated to cost $350,000. The engine is listed in the National Register of Historic Places.
Pennsylvania Railroad 1361 is a 4-6-2 K4 "Pacific" type steam locomotive built in May 1918 by the Pennsylvania Railroad's (PRR) Juniata Shops in Altoona, Pennsylvania. It hauled mainline passenger trains in Pennsylvania and commuter trains in Central New Jersey on the PRR until its retirement from revenue service in 1956. Restored to operating condition for excursion service in 1987, No. 1361 and its only surviving sister locomotive, No. 3750, were designated as the official state steam locomotives by the Pennsylvania General Assembly. In 1988, it was sidelined due to mechanical problems and was currently owned by the Railroaders Memorial Museum (RMM) in Altoona, Pennsylvania, who were currently getting No. 1361 back to operation.
The Pennsylvania Railroad G5 is a class of 4-6-0 steam locomotives built by the PRR's Juniata Shops in the mid-late 1920s. It was designed for passenger trains, particularly on commuter lines, and became a fixture on suburban railroads until the mid-1950s. The G5 was the largest and most powerful 4-6-0 locomotive, except for a single Southern Pacific 4-6-0 that outweighed it by 5,500 lb.
The Pennsylvania Railroad's class E2, E3, E7 steam locomotives were of the 4-4-2 "Atlantic" passenger type, frequently called light Atlantics after the introduction of the heavier E6 Atlantics. All were similar in size and boiler capacity but differed in firebox type, valves and valve gear and cylinder diameter. Classes E2 and E3 were built simultaneously. Starting in 1916 a rebuilding program converted ninety class E2a,b,c to class E7s by replacing slide valves with piston valves and increasing cylinder diameter from 20.5 to 22.5 inches. Fourteen class E2 were similarly converted to class E7sa. Ninety class E2a,d, E3a,d were converted to class E3sd. These improvements allowed many of the engines to remain in active service into the 1930s.
PRR 460, nicknamed the "Lindbergh Engine", is a Pennsylvania Railroad E6s steam locomotive now located in the Railroad Museum of Pennsylvania, outside of Strasburg, Pennsylvania in the United States. It was built in 1914 and became famous after racing an aircraft to New York City carrying newsreels of Charles Lindbergh's return to the United States after his transatlantic flight in 1927. In the late 1930s, No. 460 was operated by the Long Island Rail Road, and by the Pennsylvania-Reading Seashore Lines in the early 1950s, before being retired in 1953. No. 460 is the only surviving locomotive of its class and was listed on the U.S. National Register of Historic Places in 1979. From 2010 to 2016, No. 460 underwent cosmetic restoration at the Railroad Museum of Pennsylvania.
Pennsylvania Railroad 7002 is a class "E7s" 4-4-2 "Atlantic" type steam locomotive built for the Pennsylvania Railroad by their own Altoona Works in August 1902. Today, it is on display at the Railroad Museum of Pennsylvania outside of Strasburg, Pennsylvania in the United States. Originally No. 8063, the PRR renumbered it to No. 7002 after the original, claimed to be a land-speed-record-setter, was scrapped. It is the only survivor of its class and was listed on the National Register of Historic Places in 1979.
Pennsylvania Railroad 6755 is a 4-8-2 "Mountain" type steam locomotive built in 1930 for the Pennsylvania Railroad by the railroad's own Altoona Works as a member of the M1b locomotive class for mainline freight service. Retired from commercial service in 1957, the locomotive was preserved by the Pennsylvania Railroad and was placed on display at the Railroad Museum of Pennsylvania in Strasburg, Pennsylvania. The 6755 is the only M1 class locomotive to have survived into preservation.
A duplex locomotive is a steam locomotive that divides the driving force on its wheels by using two pairs of cylinders rigidly mounted to a single locomotive frame; it is not an articulated locomotive. The concept was first used in France in 1863, but was particularly developed in the early 1930s by the Baldwin Locomotive Works, the largest commercial builder of steam locomotives in North America, under the supervision of its then chief engineer, Ralph P. Johnson.
Canadian Pacific 1278 is a class "G5d" 4-6-2 "Pacific" type steam locomotive built by the Canadian Locomotive Company for the Canadian Pacific Railway. After being retired from revenue service, the locomotive was purchased in 1965 by F. Nelson Blount for excursion trains at his Steamtown, U.S.A. collection. The locomotive was sold to Gettysburg Railroad in 1987, and it pulled excursion trains between Gettysburg and Biglerville, but it was subject to shoddy maintenance by inexperienced crews. The locomotive was retired from excursion service in 1995, after suffering a firebox explosion in June. As of 2024, the locomotive is on static display at the Age of Steam Roundhouse in Sugarcreek, Ohio.
Reading 1187 is a camelback 0-4-0 switcher locomotive built in 1903 by Baldwin for the Philadelphia and Reading Railroad. It was primarily used for yard switching services, until 1946, when it was sold to the Colorado Fuel and Iron Company's E&G Brooke Plant as No. 4. In 1962, it made its way to the Strasburg Rail Road in Strasburg, Pennsylvania to be used in hauling tourist trains, but due to its small size, it was reassigned to switching passenger cars. After being removed from service in 1967, 1187 sat on display at the Railroad Museum of Pennsylvania, before sitting idle at the Strasburg yard. In 2020, it was acquired by the Age of Steam Roundhouse, who is currently giving the locomotive a cosmetic stabilization at their location in Sugarcreek, Ohio.
Canadian Pacific 972 is a preserved D-10j class 4-6-0 "Ten-wheeler" type steam locomotive built by the Montreal Locomotive Works in 1912. It was used for pulling branchline and mainline freight trains for the Canadian Pacific Railway, until it was removed from service in 1959. 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.
