Rule 308.1 — Changing Direction - Proceed Clearance

Unless otherwise provided by rules or special instructions, when authorized to proceed by clearance, a train or transfer must move only in the specified direction.

Provided the track to be operated over has not been released or a block in ABS is not re-entered, a train or transfer authorized by clearance to proceed may reverse a distance of 300 feet or less. In ABS a crew member must be in position to see the section of track to be used is clear and will remain clear of equipment or a track unit.
