Q

The QP/QMP on a diesel passenger train conducting a class 2 brake test does not observe a brake release on the rear locomotive. What could the cause and be how can this be corrected?

A

Possibly bottled air

To release bottled air

  • Open the Independant Application Release Valve
  • After air discharges, close the valve and begin class2 brake test
