Plant System 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 517 (Locobase 9501)

Data from "Richmond Ten Wheeler for the Plant System," Railway and Locomotive Engineering, March 1899, pp. 116, 123. Works numbers were 2766-2777. Rumary's list shows the railroad as the Georgia, Florida & Western, specifically, although the locomotives were labeled Plant System.

This locomotive was credited with 80 mph at several stretches in a run that covered 172 miles in 3 hours 22 minutes with a train load of 500 tons. One train of 11 cars averaged 51.3 mph on 20 April 1899.

As with many such reports at the time, the R&LE article included a list of the component suppliers:

Westinghouse brakes and train signal.

Golmar bell ringers,

Janney couplers

Star headlights

Monitor injectors

Chapman jacks

Franklin asbestos lagging

Nathan lubricators

United States metallic packing

Coale mufflers

Leach sanders

French springs

Falls hollow stay bolts

Crosby steam gages

Latrobe steel tires

National Tube Works tubes

McKee Fuller engine truck and tender wheels

American Steel Foundry Company's tender trucks

Richardson balanced valves
