PTC Controlling Assets
The PTC Controlling Assets document explains what PTC critical asset changes consist of along the NCTD’s ROW.
The Change Request Form is intended for use by anyone originating changes to PTC critical assets on the NCTD right-of-way on the LOSSAN corridor from Santa Fe Depot to the Orange County Line. Generally, the users will include designers coordinated through the implementing agency, construction management coordinated through the construction management team, and maintenance workers coordinated through their supervisors. PTC critical assets include: center line track (horizontal and vertical), insulated joints, derails, at-grade crossings (highway, street, pedestrian, private), limit signs (for example CTC, Yard), milepost marker signs, point of switch, wayside signals, speed signs, and whistle boards.
Unplanned changes that occur during construction will be managed by the Construction Management team and the Resident Engineer. Unanticipated changes that have occurred, or are occurring as a result of maintenance activities, will be used by maintenance staff to report the changes to PTC critical assets.
The Unreported Change Request Form is for use by individuals who discover unreported changes. It is expected that on occasion a railroad employee will discover changes that have occurred to track or other railroad assets due to outside influences such as vandalism, accidents, severe weather, or natural disaster. These changes may also be reported to NCTD by another entity, such as law enforcement, a new agency, or a private citizen. Regardless of how the change is detected, it should be reported immediately so that the appropriate corrective action can be taken.
Model-Approved Hardware Replacement
Model-approved hardware may be replaced without submitting a Change Request; however, the replacement must be reported through the Model-Approved Hardware Replacement Form. Inventory control labels for such items (or their packaging, as applicable) will include a Model Approval tag. Questions about the Model Approval status of a component should be directed to an employee’s supervisor.
