How physically is this done?
Normally to provide HEP , requires a constant RPM generator set , to maintain 
the 50 HZ .
Means that you cant derive the power from the main traction alternator or from 
the main prime mover.
As Im fairly sure the XPTS dont have a secondary generator, how is this 
done?Static Invertors possibly?
