	Briefly (and without consulting a reference to be sure) it's
a 12-cylinder, turbocharged, 2800-HP, 4-axle road unit, a member of the
"50 series."  Like other current EMD's, it has sophisticated wheel-slip
control, enabling it to run continuously in the creep range (just short
of slip) where adhesion is maximized.  Thus it can use all that horsepower
at lower speeds (like an SD-40).  It has, on the other hand, four fewer
cylinders to maintain than does an SD-40, and two fewer motors.  Alaska
Railroad got the first production units.
