According to man who supervised the repair on 6304 in McCloud told me that control stand was packed with dirt, there were frayed wires, and just a general mess. He was, in fact, surprised it made to McCloud at all.

For what its worth, that unit does have dynamic brakes or controls for dynamics on trailing units. When it made the Westbound trip from Reno to Colfax, they toasted the brakes on some of the cars. As they did not turn the unit to go back to Reno, one of the Amtrak P42's was on the point.
