Data from "Rogers' Six Wheel Switching Locomotive for the Western Railway of Alabama", Railway Review, Volume 36 (20 June 1896), p. 339.
Delivered three years after the Chicago & North Western switcher delivered from Schenectady and shown in Locobase 9136, this engine shared many of the same specifications. The comparison supports RR's comment that "this engine is a remarkably heavy one for yard work and it is an illustration of the tendency toward large steaming capacity for locomotives for switching service."
Rogers produced four more switchers for the WRA in 1903-1906. These used 19" diameter cylinders, steam pressed to 180 psi, and weighed 10 short tons more.
The 5 went out of service before 1907.
