[quote user="Murphy Siding"]I just don't understand who would want a switcher locomotive with only half the axles powered.[/quote] This TEM14 locomotive has all axles powered.  Earlier, someone speculated that the wheel arrangement designation stated as 2O + 2O - 2O + 2O in the manufacture’s spec sheet meant that half the axles were unpowered. However, the designation of 2O (two zero) means this:  Two axles powered, and zero axles unpowered.  It amounts to what we would call a B truck.  In U.S. terms, this locomotive would have a wheel arrangement of B+B – B+B. That means that each end of the locomotive rides on two individual trucks, each with its own independent truck frame.
