Where are permanent track speeds designated?

• A. Special Instructions
• B. Form EC-1
• C. Dispatcher Messages
• D. Schedule Book Only

Answer: (A)

Permanent track speeds are designated in Special Instructions. These instructions are published with the timetable and set fixed operating limits that apply across the network until they’re changed by another Special Instruction. They give crews the standard speeds for mainline and yard tracks that are expected to be followed on every run. Dispatcher Messages cover temporary restrictions, so they’re not used to define permanent speeds. The Schedule Book contains the timetable itself, not the ongoing speed limits, and Form EC-1 is not used for publishing permanent speeds.
