Grand Scales General Code of Operating Rules First Edition January 1, 2007

16.0 Track Warrant Control

Authority to Enter TWC Limits. 16.1 Where designated by the timetable, a track warrant will authorize main track use under the direction of the train dispatcher or as prescribed by Rule 5.0 (Yard Limits). Track warrant instructions must be followed where yard limits are in effect.

Designated Limits 16.2Track warrant limits must be designated by specific track, where required, and specific location such as switches, milepost, or railroad identifiable points. However, station names may be used as follows: a. First Named Point When a station name designates the first named point, authority extends from and includes the last siding switch. Authority extends from the station sign if no siding exists. b. Last Named Point When a station name designates the last named point, authority extends to and includes the first siding switch. Authority extends to the station sign if no siding exists.

At the last named point, authority extends to but does not include the last siding switch when the track warrant states, “Hold main track at last named point.”

Operating with Track Warrants 16.3 A track warrant authorizes a train or engine to occupy the main track within designated limits. However, the train or engine must not foul a switch at either end of the limits where an opposing train may use the same switch to clear the main track.

The train or engine must move as follows: 1. Proceed from one point to another in the direction the track warrant specifies. When a crew member informs the train dispatcher that the entire train has passed a specific point, track warrant authority is considered void up to that point. Or 2. If authorized to “work between” two specific points, the train or engine may move in either direction between those points. When a crew member informs the train dispatcher that the authority is released between two specific points, the authority is considered void between those points. This track release must begin at the outer limit of the authority.
