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).

Notes :

Signals 01, 04, 08, 12 :
 Route from these signals to signal 20A (Up Main) can only be
 cleared for trains booked to proceed through Weston and beyond.
 This route cannot be cleared for shunt moves, shunt moves from
 these signals for reversing at signal 10 must be set towards
 signal 17.

Flag location STR :
 clearing this flag is only required for movements reversing at
 signal 129.
 Through movements to Dock or Straight Road from other signals 
 do not require this flag to be cleared.

Flag location P2F :
 For moves through signal 105 requiring to run through to the
 buffer stops, this flag can be cleared when signal 105 is off
 without the need to release groundframe A.
 Shunt moves passing through or originating at flag position STR
 and requiring to move through to the buffer stops require
 groundframe A to be released.
 Local shunt moves originating in platform 2 also need
 groundframe A to be released.

Flag locations STS, GWK, GW1, GW2 and GW3 :
 these locations are mutual exclusive, only one of these locations
 can be cleared at any one time.

FPL.

Normal position is FPL locked.
