was inside-connected and the drivers were outside-connected.'-' 

 It is possible tliat more than one set of adhesion wlieels was used, 

 for Sellers said in Improvements (p. i8): "Where locomotives of 

 great power are to be constructed ... it will be necessary to 

 employ two or more sets of adhesion wheels, either geared together, 

 or connected with each other by the usual series of connecting" rods, 

 commonly used in locomotives." 



Work began in February or March 1855, for the March 29 issue 

 of the Railroad Record stated that Niles was "now building" two 

 Sellers patent locomotives for a road in Pennsylvania. '-'^ The engines 

 were built under the direct supervision of Sellers and Whetstone. 

 As work began on the engines, Trautwine reported to the directors 

 of the Coal Run company : 



The two Sellers locomotives, contracted for with Messrs. Niles & Co, 

 of Cincinnati, will, as I am advised, be ready for delivery by the stipu- 

 lated time, viz : In April next. 



I have appraised Mr. Sellers that our road will not be ready to re- 

 ceive them at that date; but I anticipate no difficulty in making arrange- 

 ments with him for storing the machines for us.'-^ 



One of the engines was given a public trial in Cincinnati in late 

 August 1855, by which time both locomotives had been completed. ^^^ 

 While the locomotives were under construction, the Coal Run 

 company was experiencing considerable difficulty, which led to its 

 failure before the railroad itself was complete. Trautwine at the 

 same time lost his right arm in an accident connected with the 

 road's construction. The locomotives were sent East at just about 

 the time of the failure. J. Snowden Bell recalled having seen as a

 was reported to C. E. Fisher by Henry F. Calvin (see Bulletin no. 42, Railway and 

 Locomotive Historical Society, p. 28). Calvin mistakenly reported that the engines 

 were originally equipped with cog gearing rather than the smooth center-rail 

 machinery.
