Lookout based methods will always have one major flaw which is the human input aspect of it. A human will always make mistakes, need a break, have issues at home, feel the cold etc.
Hazards Of Using Lookout
Automatic Track Warning Systems (ATWS) & Semi-Automatic Track Warning Systems (SATWS) systems are not subject to those humanistic qualities that lead to inadequate safety measures. These treadles based solutions are planned and installed to a high standard following all Network Rail rules and regulations. The system is SIL3 rated, meaning that statistically a failure can occur 1 in every ten thousand years, whereas sites working under Lookout assisted protection recorded 137 near misses in 2016 alone.
