Each of the stop signals listed above are either 2-aspect, 3-aspect, or 4-aspect signals, and are configured as either controlled, or automatic stop signals, as shown above.
‘Proved’ replacement facilities
The latest signalling design group standards dictate that stop signals provided with the facility to be replaced to danger, need to be provided with ‘proved’ replacement facilities. This means that none of the signalling provided on Panel 7 are that of ‘emergency replacement’ facilities.
The illumination of the associated red signal lamp indication proves that the signal is displaying a danger (red) aspect, and that the aspect can be relied upon for the purposes of Rules and Regulations.
Signals controlled by another Signaller, or Crossing Keeper
BT11, T891/LH5, and T894/LH6 stop signals are each controlled by an appropriate lever within Billingshurst signal box, or the Crossing Keepers located at Littlehaven.
Whilst the appropriate lever is positioned ‘normal’, the signal concerned will be maintained at danger (red)
Once the appropriate lever is positioned ‘revere’, the signal concerned will display the appropriate ‘proceed’ aspect providing all signalling controls have first been met.

These lamp indications, whilst illuminated, inform the Panel 7 Signaller that the appropriate signal lamp for the signal concerned is illuminated, and functioning correctly.
If at any time, these lamp indications are not illuminated, it must be assumed that the appropriate signal lamp has failed.
The failure of a signal lamp will be confirmed by the next stop signal in-rear, not displaying a ‘proceed’ aspect, once ‘cleared’.

| T893 | Down Horsham line between Littlehaven and Horsham stations |
| T896 | Up Horsham line between Horsham and Littlehaven stations |
Each of the stop signals listed above are provided with ‘clearance delayed’ lamp indications provided on Panel 7.
These lamp indications, once illuminated, inform the Panel 7 Signaller that the signalling interlocking is maintaining the signal concerned at danger, even though a route has been set, until a pre-determined condition has first been met, as described below for the signal concerned.
These lamp indications will illuminate and pulse once the appropriate route has first been set and all controlling track circuits for the signal route concerned are unoccupied, and, for the reasons explained below, the signal is being maintained at danger by the signalling interlocking.
T893 signal
Once a route has been set from T893 signal to T895 signal, one of two conditions will be applied, as described below;
T893 signal will display a ‘proceed’ aspect once the Littlehaven ‘Stopping/non-stopping’ rotary control switch has been selected to ‘non-stopping’, and the ‘confirmation’ push-button has been depressed (the confirmation button lamp will become illuminated) Under these circumstances, the ‘clearance delayed’ lamp indication will remain extinguished.
T893 signal will remain at danger once the Littlehaven ‘Stopping/non-stopping’ rotary control switch has been selected to ‘stopping’, and the ‘confirmation’ push-button has been depressed (the confirmation button lamp will become illuminated) Under these circumstances, the ‘clearance delayed’ lamp indication will become illuminated and pulse.
Once an approaching train closely approaches T893 signal, only at this time will T893 signal change and display a ‘proceed’ aspect. Once T893 signal displays a ‘proceed’ aspect, the ‘clearance delayed’ lamp indication will extinguish.
The second condition explained above, allows for the Automatic Half Barrier level crossing (AHBLC) at Parsonage Road to remain open to road traffic, whilst an approaching down line train stops and calls at Littlehaven station.
T896 signal
Once a route has been set from T896 signal to T894 signal, one of two conditions will be applied, as described below;
T896 signal will display a ‘proceed’ aspect provided there is no train closely approaching T896 signal and occupying ‘MFD’ track circuit between Horsham Junction and T896 signal.
Under these circumstances, the ‘clearance delayed’ lamp indication will remain extinguished.
T896 signal will remain at danger if an approaching train occupies ‘MFD’ track circuit before a route is subsequently set from T896 signal to T894 signal.
Alternatively, if a train has been detained at T896 signal because the signal section ahead has been occupied, then subsequently becomes unoccupied, even though a route has been set. Under these circumstances, the ‘clearance delayed’ lamp indication will become illuminated and pulse. Once T896 signal displays a ‘proceed’ aspect, the ‘clearance delayed’ lamp indication will extinguish.
Because of the close proximity of T896 signal to Parsonage Road Automatic Half Barrier level crossing (AHBLC) The second condition explained above, allows for the road traffic light sequence to initiate, and then for the half lifting barriers to lower before allowing T896 signal to display a ‘proceed’ aspect.

| T894/LH6 | Up Horsham line at Littlehaven station |
Each of the stop signals listed above are provided with ‘slot off’ lamp indications provided on Panel 7.
These lamp indications, once illuminated, inform the Panel 7 Signaller that the Crossing Keeper at Littlehaven has ‘cleared’ the signal concerned.
Panel 7 is provided with two Signal Group Replacement controls.
Each of these controls are located geographically on the signalling panel and are provided with a depress/lift button and associated lamp indications.
Horsham North Signal Group Replacement Control
The following signals if cleared will be restored to danger, if not cleared, will be maintained at danger
T834,T836,T837,T838,T839,T840,T841,T842,T843,T844,T846,T893,T885,T896,T897;
PLS T1401,T1403,T1404,T1405,T1407,T1409,T1411,T1413,T1415,T1417,T1419
Horsham South Signal Group Replacement Control
The following signals if cleared will be restored to danger, if not cleared, will be maintained at danger
T843,T845,T846,T847,T848,T849,T850,T851,T853;
PLS T1406,T1408,T1410,T1412,T1421,T1423.
Each Signal Group Replacement button has both a depress and lift function.
Lifting this button will replace to danger all controlled stop signals within that particular signal group replacement area (see the listings for each area as shown above). Once the SSI or group of SSI correctly responds to this action, the associated SSI indication lamps provided nearby will each illuminate.
Depressing this button (once lifted) will return the associated signal group replacement area to a normal state, which will allow route setting to be performed.
Once the SSI or group of SSI correctly respond to this action, the associated SSI indication lamps provided nearby will each extinguish.
