What is considered an act of vandalism in this context?

In the context of MTA operations, an act of vandalism is identified as any willful destruction or defacement of property. An unauthorized person on tracks can directly damage the infrastructure through trespassing, cause disruption to service, or create danger for themselves and others by being in a restricted area not meant for public access. This not only poses safety risks but can also lead to significant repairs or delays, thus damaging the operational integrity of the MTA system.

The other scenarios, although disruptive, do not inherently involve the active destruction or defacement of property. Disorderly passengers may create a chaotic environment, but they are not directly vandalizing property. Similarly, refusal to follow instructions, while problematic for safety protocols and operational efficiency, also does not equate to vandalism since it doesn't involve the physical destruction of property. Therefore, the presence of an unauthorized individual on the tracks clearly fits the definition of vandalism in this context, as it implies a disregard for rules that protect both people and property.
