For SEPTA Key Equipment, except the HSD, which number do you call to report an incident?

The correct answer is the number 215-580-4020, which is designated for reporting incidents related to SEPTA Key Equipment, excluding the High-Speed Drive (HSD). This specific number is established to ensure that all incidents are reported directly to the appropriate SEPTA department that can take swift action. This helps maintain the safety and reliability of the transit system.

The other options do not correspond to the correct reporting line for incidents concerning SEPTA Key Equipment. Some might be general information lines or unrelated to SEPTA, which would not effectively facilitate incident reporting. Knowing the exact designated number is critical for timely response and resolution of any issues that arise.
