[quote user="Murphy Siding"]      I thought the  A-1-A  trucks  in the early road switchers were for lowering axle loadings, but also because a good way had not been perfected to make all three axles powered.  Milwaukee could have ordered their light axle branchline switchers as A-1-A, but chose C-C instead.  In a locomotive designed for switching, wouldn't you want more tractive effort?[/quote] Yes, I think you would want all axles powered, especially on a locomotive not intended for high speed, but for heavy pulling instead. The brochure on the TEM14 says this: “The TEM14 diesel-electric shunter is designed for heavy-duty gravity shunting and moving operation.”   The wheel arrangement is stated as: 2O + 2O-2O + 2O.  Do we know for sure that that means four powered axles and four idler axles?  I am not sure what it means.  Each designation of “2O” refers to two axles and four wheels.  I am not convinced that this locomotive does not have all axles powered. The paint color scheme used on the TEM14 is widely referred to as the “Black Cardinal.”  Here is a view of the control stand: <a href="http://www.flickr.com/photos/62107343@N04/7122102635/in/set-72157629171163581">http://www.flickr.com/photos/62107343@N04/7122102635/in/set-72157629171163581</a>
