---

Feedback:
Adjust/verify the regulating valve setting to 105 psi on trains consisting entirely of business cars or passenger equipment. A locomotive with the regulating valve adjusted to 105 psi that will not be used in train consisting entirely of business or passenger equipment will need to have the regulating valve adjusted back to 90 psi. Rule 101.8: Reducing Locomotive Overcharge outlines the process to do so.
