The table below shows the required locking positions.
A lever number or name followed by 'N' means the lever must be in normal position.
Followed by 'R' means the lever must be in reversed position.
Lever no. followed by * indicate locking for flank protection or overlap protection. Note that the position of these levers may sometimes be either normal or reverse, but the lever is locked in that position when the signal is cleared.
Signals in opposite direction giving direct access to the route as indicated must always be at danger and are not explicitly listed in the table below. Signals in opposite direction which do not give direct access but must be at danger for overlap protection are included, and are indicated by *.

Column "calling on" indicates if the signal can be cleared on occupied track. 
When signal requires 'caution', the signal must be kept at danger until the speed of the train is sufficiently reduced (approx. 10 mph).
