What is the purpose of an Operations Notice (ON)?

The purpose of an Operations Notice (ON) is to provide advisory or cautionary information related to operations. This encompasses notifications about changes in operational procedures, safety considerations, and critical information that may affect train operations. These notices ensure that all employees are informed of current conditions that might impact the running of the service, such as weather-related disruptions, equipment conditions, or other significant operational issues. By communicating this information effectively, the MTA can maintain safety and efficiency across its services.

The other choices do not represent the role of an Operations Notice. For instance, train schedule updates are typically conveyed through other official channels or documents designed for permanent changes. Listing delays and disruptions in service is usually managed through customer service announcements or system status updates rather than an ON. Training materials for new recruits are typically distinct documents unrelated to operational advisories.
