Answer 2

It means that stretch of track is under track warrant control.  Its a form you fill out upon instruction  from the dispatcher.  It gives your train the authority to occupy a certian section of track.

Answer 3

Track warrant control territory.  Crew needs to be issued a track warrant to move their train in those limits...usually issued by a train dispatcher.

Answer 4

Track Warrant Control (TWC) is a verbal authorization system defined by the General Code of Operation Rules (GCOR), used to authorize trains to occupy Main Tracks. TWC can be used as a stand-alone dispatching and safety system in unsignaled territories, or can be supplemented with Automatic Block Signaling (ABS) to increase flexibility and traffic capacity
