| Since the earliest days of railroads' use of the internal combustion engine, nearly every 
manufacturer of industrial or military locomotives has produced some form of end-cab motive 
power. They have ranged in size from small two-ton mining "mules" to heavy-duty industry 
workhorses which tipped the scales at nearly 100 tons. Additionally, some of the builders 
could trace their heritage back to the mid to late 1800s as suppliers of farm implements, 
industrial machines or railroading equipment. Moreover, four of the small locomotive builders 
had a history of manufacturing steam locomotives -- Baldwin, Davenport, Porter and Vulcan.
 
Mainline and short line railroading by the mid-1940s had clearly demonstrated that the 
end-cab was preferred for yard and branchline work.  Contrastingly, industrial and military 
users often maintained a preference for center-cab power. Thus, the number of new end-cab 
models to appear in builder catalogues diminished until the 1990s and the push for green 
technology. |
