Kansas City & Independence Rapid Transit 2-4-2 "Columbian" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class Pocahontas (Locobase 11620)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 13, 227 and Volume 15, p. 82 Works numbers were 8528-8529 in April 1887; 8670, 8675, 8679 in July; 9976 in May 1889 and 10049 in June.

As with most street railways, the purchase and operation of these steam dummies spanned only a short period in the motive power history of the KC&IRT. The first was produced in April 1887; the two built in April were named Pocahontas and Minehaha. Three more were delivered in July. The last of these was sold to the East End Railway either immediately or soon after it went into service. The first of the 1889 steam dummies was number 5 as well.

By 1892, the company had decided to electrify and the stud of dummies was sold off, most to lumber companies.
