Trevithick Locomotive, 1804 



The National Museum's nonoperable model shown in 

 figure 61 represents the probable form of the first rail 

 locomotive of Richard Trevithick, the Cornish engineer who 

 was one of the early advocates of the high-pressure steam 

 engine. The Museum's model (USNM 180058) is about 20 

 inches in length, and its flywheel is about 10 inches in diam- 

 eter. It was obtained in 1888 from its builder D. Ballauf, a 

 model maker often employed by the Museum.
