General Notes 

GREAT CARE SHOULD BE TAKEN TO ALIGN THE SIGNAL IN STRICT 

ADHERENCE TO THE SIGNAL SIGHTING FORM REQUIREMENTS 

The Signal Sighting Form (SSF) will provide the definitive, signal specific alignment 

details and should always be consulted prior to commencement of work.  

 

Where the centre of the most restrictive aspect is greater than 2750mm above the 

LH running rail, the signal is generally aligned to a target board (PADS Number 

086/011540) at a point detailed in the Signal Sighting Form.
