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).

Level crossing.

Level crossing gates are operated by 102, locks are operated by 101.
'Open' position is 102R and 101R.

To close level crossing, close the gates (102N), then set the lock (101N).
To open level crossing, release the lock (101R) and open the gates (102R).

The following signals require the LC to be closed before these can be cleared and will lock the LC when cleared :
105
113
121
123
136
137

The following switches require the LC to be closed before they can be set to diverge (reversed), and will lock the LC if reversed :
114
120
125

Notes :
signals 203/206 :
signal 203 can only be cleared for trains which are booked
continue onward to Marazion, signal 206 must be used for
all local moves.

Level crossing.

Level crossing gates are operated by 264, locks are operated by 263.
'Open' position is 264R and 263R.

To close level crossing, close the gates (264N), then set the lock (263N).
To open level crossing, release the lock (263R) and open the gates (264R).

The following signals require the LC to be closed before these can be cleared and will lock the LC when cleared :
202
203
206
213
223
252
261

The following switches require the LC to be closed before they can be set to diverge (reversed), and will lock the LC if reversed :
245
