When more than one main track is in service, what must be recorded on the Form EC-1?

• A. Track number or name designated in authority.
• B. The time of day.
• C. The train's engine number.
• D. The dispatcher's initials.

Answer: (A)

The main idea is that when more than one main track is in service, the Form EC-1 must specify exactly which track is authorized. This is done by recording the track number or name designated in the authority. Clearly identifying the track under authority ensures everyone knows where movements are permitted and prevents trains from entering the wrong main track. Other details like time of day, engine number, or dispatcher's initials don’t identify which main track is authorized, so they aren’t the required information for this purpose.
