   From the sounds of it, they should be getting one per month from now   
   until 2016:

   They will be more energy efficient according to Siemens:

   Also, as part of the reliability improvements, these will have remote   
   monitoring and Siemens will be able to determine what might be wrong   
   with a locomotive before it fails, and change out a component at the end   
   of a run:
