Pennsylvania Railroad 6755

The Pennsylvania Railroad's class A5s was the most powerful class of 0-4-0 steam locomotives. The Pennsylvania Railroad built 47 in its Juniata Shops between 1916–1924. They were all retired by 1957. One is preserved at the Railroad Museum of Pennsylvania.

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.

Pennsylvania Railroad 520 is a 2-8-2 "Mikado" type steam locomotive built in 1916 by the Baldwin Locomotive Works for the Pennsylvania Railroad for freight duties as a member of the L1s class. In 1942, the locomotive was involved in a devastating boiler explosion incident that required construction of a new, replacement boiler. After being retired in 1957, the locomotive was saved for preservation and placed on display at the Railroad Museum of Pennsylvania in Strasburg, Pennsylvania, and was listed on the National Register of Historic Places in 1979.

The Pennsylvania Railroad's class H8, H9s and H10s steam locomotives were of the 2-8-0 "Consolidation" type, the last three classes of such built by the railroad. The three classes differed only in cylinder diameter and thus tractive effort, each subsequent class increasing that measurement by an inch. The first H8 was built in 1907 and the last H10 in 1916; within a few years they were replaced on heavy freight assignments by 2-8-2s and 2-10-0. They became the railroad's standard light freight locomotive, replacing all other class H 2-8-0s, and a number remained in service until the end of PRR steam locomotive operation in 1957. 968 class H8 of various subclasses were constructed, along with 274 class H9s and 273 class H10s. A number of H8 locomotives were rebuilt to H9s specification. Class H10s was built primarily for PRR Lines West, and featured a typical Lines West tender with sloping side coal boards at the top, to enable a bigger load of coal to be carried. Some locomotives of this type were leased to the PRR-owned Long Island Rail Road, becoming the primary freight-hauling type on that system.

The Pennsylvania Railroad's class H6, H6a, and H6b steam locomotives were of the 2-8-0 "Consolidation" freight type, the most numerous class on the railroad with 1,707 units and the second most prolific 2-8-0 class in North America, with the USATC S160 class rostering 88 units more. The three subclasses differed as follows: In the 1920s, 699 H6a and H6b had superheaters added, and cylinder size increased from 22 in (560 mm) to 23 in (580 mm). These rebuilt units were reclassified to H6sa and H6sb. Class H6 were used throughout the system as mainline freight haulers, on local freights, and as switchers in yards. They were frequently seen double- and tripleheading long freight trains up the steep grades on the Pennsy.During the period when the PRR was building the H-6 class, the railroad had effective stock control of the Baltimore and Ohio Railroad, and installed a PRR vice-president Leonor F. Loree, as president of the B&O. Subsequently, the B&O bought a large group of identical locomotives from the American Locomotive Company; these were initially classified class I-4, later becoming class E-24. The E-24 class had many variations, some being converted to switchers, or receiving superheaters and new valve chests. The E-24a was equivalent to the PRR H-6sb. None of the B&O E-24 class survived to the diesel era.

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 (notably the Long Island Rail Road) 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.

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 No. 1223 is a class "D16sb" 4-4-0 "American" type steam locomotive built in November 1905 for the Pennsylvania Railroad by their own Altoona Works for passenger service. After being retired from active service in 1950, the locomotive ran excursion trains on the Strasburg Rail Road outside of Strasburg, Pennsylvania from 1965 to 1989 when it was removed from service requiring firebox repairs. Currently, the locomotive is still on static display at the Railroad Museum of Pennsylvania outside of Strasburg. It was listed on the National Register of Historic Places in 1979. No. 1223 is the only surviving example of the Pennsylvania Railroad's D16sb class.

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.

The Railroad Museum of Pennsylvania is a railroad museum in Strasburg, Lancaster County, Pennsylvania. The museum is located on the east side of Strasburg along Pennsylvania Route 741. It is administered by the Pennsylvania Historical and Museum Commission with the active support of the Friends of the Railroad Museum of Pennsylvania (FRM). The museum's collection has more than 100 historic locomotives and railroad cars that chronicle American railroad history. Visitors can climb aboard various locomotives and cars, inspect a 62-ton locomotive from underneath, view restoration activities via closed-circuit television, enjoy interactive educational programs, and more. The Railroad Museum of Pennsylvania was created to provide a historical account of railroading in Pennsylvania by preserving rolling stock, artifacts, and archives of railroad companies of the Commonwealth. However, the museum has branched out over the years, acquiring some pieces that are not directly related to Pennsylvania, but are important to the history of railroading. In addition to full-size rolling stock pieces, a smaller exhibit gallery is on the second floor. The museum offers a number of other attractions, including several model railroad layouts, a hands-on educational center, and a library and archives.

The Strasburg Rail Road (reporting mark SRC) 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. Strasburg has five operational steam locomotives on its roster, as well as several others in various stages of restoration. As of 2022, Canadian National No. 89, Norfolk & Western No. 475 and Brooklyn Eastern District Terminal No. 15 (rebuilt as Thomas the Tank Engine) are all in active service, while Canadian National No. 7312 is currently undergoing restoration back to operation and Great Western No. 90 is undergoing its FRA inspection and overhaul as of January 2024. The other steam locomotive is 15” Gauge 4-4-0 built by Cagney in the early 1900s. They also have the nation's largest operating fleet of historic wooden passenger coaches. It hosts 300,000 visitors per year.The Strasburg Rail Road is one of the few railroads in the U.S. sometimes using steam locomotives to haul revenue freight trains. The nearby Railroad Museum of Pennsylvania occasionally uses Strasburg Rail Road tracks to connect to the Amtrak Philadelphia-to-Harrisburg Main Line junction in Paradise, Pennsylvania.

The Choo Choo Barn is a 1,700-square-foot (160 m2) train display in Strasburg, Pennsylvania, in the United States, consisting of over 150 hand-built animated figures and vehicles and 22 operating trains.
