Which document contains line and system special instructions affecting train movements?

The correct document that contains line and system special instructions affecting train movements is the Employee Special Instructions. This document is crucial for conductors and other train personnel as it provides specific guidelines and instructions that are critical for safe and efficient train operations on particular routes. These instructions may include adjustments for track conditions, safety protocols, or special operational scenarios that pertain to specific lines or systems.

This ensures that train crew members are well-informed about current conditions and can manage train movements accordingly, ultimately contributing to the overall safety and efficiency of the transit system. Employee Special Instructions often supplement other operational documents and are essential for regular updates that affect service.
