Unspecified 4-4-0 "American" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class Grant - 1873 (Locobase 4405)

This is described as a typical American-type locomotive of the time. Illustrations show an extended wagon top boiler, steam dome just ahead of the cab, wide-spread leading truck with horizontal cylinders, and a slender stack with diamond spark arrester.


Class Grant - 1884 (Locobase 10020)

Data from Park Benjamin (Ed), Appleton's Cyclopedia of Applied Mechanics (New York: D Appleton & Company, 1884), p. 341. Boiler pressure is an estimate.

Like an earlier Grant locomotive shown in Locobase 4405, this is a catalogue engine. The viewer sees no hint of what railroad, if any, might have owned it. It is a typical American-type locomotive of the time. Illustrations show an extended wagon top boiler, steam dome just ahead of the cab, wide-spread leading truck with horizontal cylinders, and a slender stack with diamond spark arrester.


Class Hinkley - 1884 (Locobase 10021)

Data from Park Benjamin (Ed), Appleton's Cyclopedia of Applied Mechanics (New York: D Appleton & Company, 1884), p. 341. Boiler pressure is an estimate.

This is a catalogue engine like the Grants shown in Locobases 4405 and 10020. The viewer sees no hint of what railroad, if any, might have owned it. It is a typical American-type locomotive of the time. Illustrations show an extended wagon top boiler, steam dome just ahead of the cab, wide-spread leading truck with horizontal cylinders, and a slender stack with diamond spark arrester.
