At the conclusion of the exposition it was again placed in 

 service with the Empire State Express, but was later with- 

 drawn because, although having great speed with a light 

 train, it lacked the pulling power required for the larger and 

 heavier trains then coming into use. Today, the 999, altered 

 somewhat, and with smaller driving wheels than when built, 

 is preserved by the New York Central System as one of its 

 historic relics. It is usually to be seen at the CoUinwood shops 

 near Cleveland, Ohio, but it still occasionally appears at 

 fairs and expositions. 



Designed by the superintendent of motive power, William 

 Buchanan, and constructed at the West Albany shops of the 

 New York Central, the 999 is of the 4-4-0, or American, type 

 and was fitted originally with 86-inch driving wheels. The 

 bore and stroke of the cylinders are 19 and 24 inches, respec- 

 tively, and a steam pressure of 180 pounds per square inch 

 was used. The fuel was bituminous coal. The extreme wheel- 

 base is 287 inches, and the distance between the two driving 

 axles is 102 inches. The weight of the locomotive is 124,000 

 pounds, that of the loaded tender is 80,000. 



American-Type Locomotive of about 1 900 



Through the bequest in 1955 of John Semple Clarke, a 

 model (figure 70) formerly lent by him to the Museum has 

 been added to the collection (USNM 314615). A 4-4-0 of 

 exquisite workmanship in brass and steel, the model is 21 

 inches long and has a gauge of 2^2 inches. 



It was constructed during the 7-year period from 1907 to 

 1914 by George Boshart, a toolmaker of Brookline, near 

 Philadelphia, Pa. All rotating and reciprocating parts are 

 operable, though the boiler is apparently not capable of 

 generating steam. There is no tender with the locomotive, 

 none having been built. 



It is not definitely known what, if any, original locomo- 

 tive the model represents, but some of its details are simi- 

 lar to those of locomotives built at the turn of the century 

 by the Schenectady Locomotive Works. While it has been 

 stated that Boshart patterned the model after a Pennsyl-
