The Eurorunner family of locomotives are a series of medium- to high-power diesel-electric locomotives built by Siemens for the European market.
 Introduced from 2002 onwards, they share design characteristics with the successful Eurosprinter range of electric locomotives, also built by Siemens.
The New York Locomotive Works, sometimes known as the Rome Locomotive Works, was a nineteenth century builder of steam locomotive engines located at Rome, New York.
 The company was active under various ownerships in building steam locomotives from 1882 until 1911.
 The New York Locomotive Works should not be confused with the earlier Breese, Kneeland, and Company which traded under the same name in the 1850s.
 The company was organized in 1881 with T. G Noch, a prominent local businessman as president.
 J. A. Durgan, a well known designer of steam locomotives was appointed superintendent, a position he had previously held at the Rhode Island Locomotive Works.
 The company was an instant success, as railroads were expanding a feverish pace.
 NYLW offered a robust, no frills locomotive and was well connected with banking interests that allowed sales along the "Car Trust Plan" with payments out to ten years.
The Baldwin Locomotive Works was an American builder of railroad locomotives.
 It was originally located in Philadelphia, and later moved to nearby Eddystone, Pennsylvania.
 Although the company was very successful as the largest producer of steam locomotives, its transition to the production of diesels was far less so.
 Later, when the early demand for diesel locomotives to replace steam tapered off, Baldwin could not compete in the marketplace.
 It stopped producing locomotives in 1956 and went out of business in 1972, having produced over 70,000 locomotives, the vast majority powered by steam.
The Siemens Asiarunner locomotives are contemporaries to the Eurorunner class and are designed specifically for the South-East Asian market - in particular metre gauge - key features are a Co'Co' wheel arrangement (resulting in low axle loads) and good clearance (see Loading gauge)
William Mason (September 2, 1808 – May 21, 1883) was a master mechanical engineer and builder of textile machinery and railroad steam locomotives.
 He founded Mason Machine Works of Taunton, Massachusetts.
 His company was a significant supplier of locomotives and rifles for the Union Army during the American Civil War.
 The company also later produced printing presses.
SNCB Class 27 was the first of the large 1980s family of 144 electric locomotives.
 The family was made up of Classes 11 (12), 12 (12), 21 (60) and 27 (60).
 Classes 11, 12 and 21 were nearly twice as powerful as Classes 22, 23 and 25.
 Class 27 was more than twice as powerful as the 1950s locomotives.
 This family was heavily influenced by the Class 20² locomotives built in the mid 1970s.
 They are very reliable because of the trial and error development of their predecessor.
 This family came into service with M4 and M5 coaching stock and the AM 80 and AM 86 series of EMUs.
 This generation was a major modernization of the SNCB even if the older M2 coaching stock remained active for more than a decade.
 These four sister classes are visually identical except for a few minor details.
 Class 11's livery is specific to the Benelux service on which they operated on for most of their service lives.
SNCB's Class 12 locomotives were dual-voltage (25000 V, 50 Hz AC and 3000 V DC) electric lomotives built for cross-border service into France.
 They were based on the single-voltage Class 21 locomotives.
 They are part of the large 1980s family of 144 electric locomotives.
 The family was made up of Classes 11 (12), 12 (12), 21 (60) and 27 (60).
 Classes 11, 12 and 21 were nearly twice as powerful as Classes 22, 23 and 25.
 Class 27 was more than twice as powerful as the 1950s locomotives.
 This family was heavily influenced by the Class 20² from the mid-1970s.
 They were very reliable because of the trial and error development of their predecessor.
 This family came into service with M4 and M5 coaching stock and the AM 80 and AM 86 series of EMUs.
 This generation was a major modernization of the SNCB even if the older M2 coaching stock remained active for more than a decade before being replaced.
 The only real difference between a Class 12 and a Class 21 was the Class 12 had a transformer inside to allow working under both 3000 V DC in Belgium and 25000 V AC plus French signalling and train protection for working in France.
 Externally they were identical except for a few details.
SNCB Class 21 is part of the large 1980s family of 144 electric locomotives.
 The family was made up of Classes 11 (12), 12 (12), 21 (60) and 27 (60).
 Classes 11, 12 and 21 were nearly twice as powerful as Classes 22, 23 and 25 while Class 27 was more than twice as powerful as the 1950s locomotives.
 This family was heavily influenced by the Class 20 from the mid-1970s.

 Class 11's bordeaux and yellow livery is specific to the Benelux service which they powered for most of their service lives.
Siemens AG (] ) is a German conglomerate company headquartered in Berlin and Munich and the largest industrial manufacturing company in Europe with branch offices abroad.
Plymouth Locomotive Works was a US builder of small railroad locomotives. All Plymouth locomotives were built in a plant in Plymouth, Ohio until 1997 when the company was purchased by Ohio Locomotive Crane and production moved to Bucyrus, Ohio in 1999.
 Production of locomotives has now ceased, and rights to the spare parts business have been sold to Williams Distribution.
