Toledo, Cincinnati & Saint Louis 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 91 (Locobase 16422)

Data from "Narrow-Gauge Mogul Locomotive", Railroad Gazette, Volume XV [15] (3 August 1883), p. 509. See also Bob Holdgreve, "Window to the Past-A narrow-gauge railroad", at [], last accessed 11 April 2019. Works numbers were 906, 918-919 in May 1883, 929-930 in June.

Holdgreve's detailed reconstruction of the founding, construction, and operation of the Toledo, Delphos & Indianapolis originally appeared in the Delphos, Indiana Herald on 19 December 1998. It provides an illuminating background to the narrow-gauge empire that was to be theToledo, Cincinnati & St Louis, aka "The Little Giant".

He continues with the TC&StL's almost immediate difficulty navigating the aftermath of the Panic of 1883 and its emergence as the Toledo, St Louis & Kansas City standard-gauge railroad, better known as the Clover Leaf Route.

As part of its expansion, the TC&StL ordered thirteen of these skinny-rail wood-burning Moguls for delivery in 1883. Eight of those were either diverted before delivery and appear under the railroads that bought them from either E B Phillips or Brooks. Sources differ about the destination of the 90, which went on display at the Exposition of Railway Appliances in Chicago. It may have first gone to the Cincinnati & Eastern, then to the Florida Southern.

The other five arrived on the TC&StL when leased by the receiver. When the TC&StL reappeared as the Toledo, Saint Louis & Kansas City, the new board chose to adopt standard gauge. Such small engines would be out of place as road engines on the wider right of way, so the TSL&KC removed the leading truck in 1889, converting all five to 0-6-0 switchers.

95 suffered a boiler explosion in September 1890, but returned to service. It was sold. By 1898, the other four had been retired.
