All trains are required to obtain a ___________ prior to initiating movement on main track (GCOR 6.2)

• A. Track Warrant for Bulletins
• B. Track Warrant
• C. Bulletins
• D. Clearance

Answer: (A)

The key idea is that moving on the main track requires explicit dispatcher authorization, and when there are temporary instructions in effect, those instructions must be bundled with the authority. In GCOR 6.2, trains entering the main track obtain a Track Warrant for Bulletins. This document provides the official permission to occupy the main track and also carries any current bulletins—such as speed restrictions, temporary speed changes, or track conditions—that apply to that movement. Having both the authority and the applicable bulletins in one form prevents miscommunication and ensures the crew acts under the latest instructions.

Bulletins alone don’t authorize movement, and a plain Track Warrant might not include the bulletins. A clearance isn’t the standard instrument used here under GCOR. So the Track Warrant for Bulletins is the correct, complete authorization needed before initiating movement on the main track.
