Facilities applied; and/or
 where the Signal has more than one Route available, identify the Route to the
Worksite and apply Blocking Facilities to protect all entry points;

Controller, the Crank Handle has been removed. The purpose of this precaution is
to prevent entry of Rail Traffic into the limits of the Worksite;
 the blocking Authority or identification number from the Train Control System;
 identification of the Points Secured;
 the PO’s name and contact details;
