Figure 68. — Operable model of an American-type locomotive of about 1 890. 



period of about 1890. This class of locomotive was built by 

 the Schenectady Locomotive Works to the New York Cen- 

 tral's design, and had 78-inch driving wheels, cylinders with 

 a bore of 19 inches and a stroke of 24 inches, and weighed 

 120,000 pounds. 



Work on this model was commenced by the donor, the late 

 Robert E. M. Bain, in 1916, and it was completed about 

 three years later, only spare time having been employed in 

 its construction. The model was given to the Museum in 

 1928. The length of the locomotive and tender is 80 inches, 

 the gauge is 6V2 inches, the diameter of the driving wheels is 

 8^16 inches, and the bore and stroke of the cylinders are IV2 

 and 3 inches, respectively. 



The brakes on the model are inoperative, as the actuating 

 cylinders for the brake system are dummies. On the other 

 hand, such parts as the boiler, firebox, steam gauge, water 

 gauge, throttle, and valve motion are all operable, and the 

 donor has asserted that there is even ring packing in the cyl- 

 inders. Although capable of being fired and steamed up, 

 using coal as the fuel, the locomotive has never been 

 operated.
