Conrail / Amtrack

Is it normal to see a conrail engine pulling an amtrack passenger train? Beacuse i was coming home and say it on a road crossin in minoa

Need answers to this question

Either the Amtrak engine broke down en route,or Amtrak is using it for a helper unit.

Here is an example on an Amtrak angine breaking down, leaving a Union Pacific SD70M to lead the train.

Picture not mine.

G E…That’s really a great night picture.
