Figure 47. — Earliest known photo of Pioneer, showing it at work in bridge con- 

 struction at Rockford, III., in 1 869. 



The Pioneer had a full and active life, for it was in oper- 

 ation 12 years prior to its acquisition by the Galena road 

 and 26 years after (figure 47). It was at one time temporarily 

 lent to the new Chicago, Burlington and Quincy line, until 

 that company was able to buy an engine of its own, and was 

 finally retired by the Chicago and North Western in 1874. 



The Pioneer is a typical Baldwin design of the period. A 

 wood burner, it weighs 10 tons, has slightly inclined cylin- 

 ders 11 by 18 inches in size, one pair of 54-inch driving 

 wheels at the rear, and a 4-wheeled swiveling truck at the 

 front. The cylinder bore was originally 10 inches, but in 

 1872 the Chicago and North Western changed it to the pres- 

 ent slightly larger dimension.
